class Aws::ElastiCache::Client

An API client for ElastiCache. To construct a client, you need to configure a `:region` and `:credentials`.

client = Aws::ElastiCache::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

See {#initialize} for a full list of supported configuration options.

@param [Hash] options
@option options [required, Aws::CredentialProvider] :credentials
  Your AWS credentials. This can be an instance of any one of the
  following classes:

  * `Aws::Credentials` - Used for configuring static, non-refreshing
    credentials.

  * `Aws::SharedCredentials` - Used for loading static credentials from a
    shared file, such as `~/.aws/config`.

  * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.

  * `Aws::AssumeRoleWebIdentityCredentials` - Used when you need to
    assume a role after providing credentials via the web.

  * `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an
    access token generated from `aws login`.

  * `Aws::ProcessCredentials` - Used for loading credentials from a
    process that outputs to stdout.

  * `Aws::InstanceProfileCredentials` - Used for loading credentials
    from an EC2 IMDS on an EC2 instance.

  * `Aws::ECSCredentials` - Used for loading credentials from
    instances running in ECS.

  * `Aws::CognitoIdentityCredentials` - Used for loading credentials
    from the Cognito Identity service.

  When `:credentials` are not configured directly, the following
  locations will be searched for credentials:

  * `Aws.config[:credentials]`
  * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
  * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
  * `~/.aws/credentials`
  * `~/.aws/config`
  * EC2/ECS IMDS instance profile - When used by default, the timeouts
    are very aggressive. Construct and pass an instance of
    `Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to
    enable retries and extended timeouts.

@option options [required, String] :region
  The AWS region to connect to.  The configured `:region` is
  used to determine the service `:endpoint`. When not passed,
  a default `:region` is searched for in the following locations:

  * `ENV['AWS_REGION']`
  * `ENV['AMAZON_REGION']`
  * `ENV['AWS_DEFAULT_REGION']`
  * `~/.aws/credentials`
  * `~/.aws/config`

  When `true`, an attempt is made to coerce request parameters into
  the required types.

@option options [Boolean] :correct_clock_skew (true)
  Used only in `standard` and adaptive retry modes. Specifies whether to apply
  a clock skew correction and retry requests with skewed client clocks.

@option options [Boolean] :disable_host_prefix_injection (false)
  Set to true to disable SDK automatically adding host prefix
  to default service endpoint when available.

@option options [String] :endpoint
  The client endpoint is normally constructed from the `:region`
  option. You should only configure an `:endpoint` when connecting
  to test or custom endpoints. This should be a valid HTTP(S) URI.

@option options [Integer] :endpoint_cache_max_entries (1000)
  Used for the maximum size limit of the LRU cache storing endpoints data
  for endpoint discovery enabled operations. Defaults to 1000.

  is not set, logging will be disabled.

@option options [Integer] :max_attempts (3)
  An integer representing the maximum number attempts that will be made for
  a single request, including the initial attempt.  For example,
  setting this value to 5 will result in a request being retried up to
  4 times. Used in `standard` and `adaptive` retry modes.

@option options [String] :profile ("default")
  Used when loading credentials from the shared credentials file
  at HOME/.aws/credentials.  When not specified, 'default' is used.

@option options [Proc] :retry_backoff
  A proc or lambda used for backoff. Defaults to 2**retries * retry_base_delay.
  This option is only used in the `legacy` retry mode.

@option options [Float] :retry_base_delay (0.3)
  The base delay in seconds used by the default backoff function. This option
  is only used in the `legacy` retry mode.

@option options [Symbol] :retry_jitter (:none)
  A delay randomiser function used by the default backoff function.
  Some predefined functions can be referenced by name - :none, :equal, :full,
  otherwise a Proc that takes and returns a number. This option is only used
  in the `legacy` retry mode.

  @see https://www.awsarchitectureblog.com/2015/03/backoff.html

@option options [Integer] :retry_limit (3)
  The maximum number of times to retry failed requests.  Only
  ~ 500 level server errors and certain ~ 400 level client errors
  are retried.  Generally, these are throttling errors, data
  checksum errors, networking errors, timeout errors, auth errors,
  endpoint discovery, and errors from expired credentials.
  This option is only used in the `legacy` retry mode.

@option options [Integer] :retry_max_delay (0)
  The maximum number of seconds to delay between retries (0 for no limit)
  used by the default backoff function. This option is only used in the
  `legacy` retry mode.

@option options [String] :retry_mode ("legacy")
  Specifies which retry algorithm to use. Values are:

  * `legacy` - The pre-existing retry behavior.  This is default value if
    no retry mode is provided.

  * `standard` - A standardized set of retry rules across the AWS SDKs.
    This includes support for retry quotas, which limit the number of
    unsuccessful retries a client can make.

  * `adaptive` - An experimental retry mode that includes all the
    functionality of `standard` mode along with automatic client side
    throttling.  This is a provisional mode that may change behavior
    in the future.

@option options [String] :secret_access_key

@option options [String] :session_token

@option options [Boolean] :stub_responses (false)
  Causes the client to return stubbed responses. By default
  fake responses are generated and returned. You can specify
  the response data to return or errors to raise by calling
  {ClientStubs#stub_responses}. See {ClientStubs} for more information.

  ** Please note ** When response stubbing is enabled, no HTTP
  requests are made, and retries are disabled.

@option options [Boolean] :validate_params (true)
  When `true`, request parameters are validated before
  sending the request.

@option options [URI::HTTP,String] :http_proxy A proxy to send
  requests through.  Formatted like 'http://proxy.com:123'.

@option options [Float] :http_open_timeout (15) The number of
  seconds to wait when opening a HTTP session before raising a
  `Timeout::Error`.

@option options [Integer] :http_read_timeout (60) The default
  number of seconds to wait for response data.  This value can
  safely be set per-request on the session.

@option options [Float] :http_idle_timeout (5) The number of
  seconds a connection is allowed to sit idle before it is
  considered stale.  Stale connections are closed and removed
  from the pool before making a request.

@option options [Float] :http_continue_timeout (1) The number of
  seconds to wait for a 100-continue response before sending the
  request body.  This option has no effect unless the request has
  "Expect" header set to "100-continue".  Defaults to `nil` which
  disables this behaviour.  This value can safely be set per
  request on the session.

@option options [Boolean] :http_wire_trace (false) When `true`,
  HTTP debug output will be sent to the `:logger`.

@option options [Boolean] :ssl_verify_peer (true) When `true`,
  SSL peer certificates are verified when establishing a
  connection.

@option options [String] :ssl_ca_bundle Full path to the SSL
  certificate authority bundle file that should be used when
  verifying peer certificates.  If you do not pass
  `:ssl_ca_bundle` or `:ssl_ca_directory` the the system default
  will be used if available.

@option options [String] :ssl_ca_directory Full path of the
  directory that contains the unbundled SSL certificate
  authority files for verifying peer certificates.  If you do
  not pass `:ssl_ca_bundle` or `:ssl_ca_directory` the the
  system default will be used if available.

add_tags_to_resource(params = {}, options = {}) click to toggle source

A tag is a key-value pair where the key and value are case-sensitive. You can use tags to categorize and track all your ElastiCache resources, with the exception of global replication group. When you add or remove tags on replication groups, those actions will be replicated to all nodes in the replication group. For more information, see [Resource-level permissions].

For example, you can use cost-allocation tags to your ElastiCache resources, Amazon generates a cost allocation report as a comma-separated value (CSV) file with your usage and costs aggregated by your tags. You can apply tags that represent business categories (such as cost centers, application names, or owners) to organize your costs across multiple services.

For more information, see [Using Cost Allocation Tags in Amazon ElastiCache] in the *ElastiCache User Guide*.

[1]: docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/IAM.ResourceLevelPermissions.html [2]: docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Tagging.html

`arn:aws:elasticache:us-west-2:0123456789:snapshot:mySnapshot`.
ElastiCache resources are *cluster* and *snapshot*.

For more information about ARNs, see [Amazon Resource Names (ARNs) and
Amazon Service Namespaces][1].

Makes a copy of an existing snapshot.

<note markdown=“1”> This operation is valid for Redis only.

</note>

Users or groups that have permissions to use the `CopySnapshot` operation can create their own Amazon S3 buckets and copy snapshots to it. To control access to your snapshots, use an IAM policy to control who has the ability to use the `CopySnapshot` operation. For more information about using IAM to control the use of ElastiCache operations, see [Exporting Snapshots] and [Authentication &amp; Access Control].

You could receive the following error messages.

**Error Messages**

  • **Error Message:** The S3 bucket %s is outside of the region.

    Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see [Step 1: Create an Amazon S3 Bucket] in the ElastiCache User Guide.

  • **Error Message:** The S3 bucket %s does not exist.

    Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see [Step 1: Create an Amazon S3 Bucket] in the ElastiCache User Guide.

  • **Error Message:** The S3 bucket %s is not owned by the authenticated user.

    Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see [Step 1: Create an Amazon S3 Bucket] in the ElastiCache User Guide.

  • **Error Message:** The authenticated user does not have sufficient permissions to perform the desired activity.

    Solution: Contact your system administrator to get the needed permissions.

  • **Error Message:** The S3 bucket %s already contains an object with key %s.

    Solution: Give the `TargetSnapshotName` a new and unique value. If exporting a snapshot, you could alternatively create a new Amazon S3 bucket and use this same value for `TargetSnapshotName`.

  • Error Message: ElastiCache has not been granted READ permissions %s on the S3 Bucket.

    Solution: Add List and Read permissions on the bucket. For more information, see [Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket] in the ElastiCache User Guide.

  • Error Message: ElastiCache has not been granted WRITE permissions %s on the S3 Bucket.

    Solution: Add Upload/Delete permissions on the bucket. For more information, see [Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket] in the ElastiCache User Guide.

  • Error Message: ElastiCache has not been granted READ_ACP permissions %s on the S3 Bucket.

    Solution: Add View Permissions on the bucket. For more information, see [Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket] in the ElastiCache User Guide.

@option params [required, String] :source_snapshot_name

The name of an existing snapshot from which to make a copy.

@option params [required, String] :target_snapshot_name

A name for the snapshot copy. ElastiCache does not permit overwriting
a snapshot, therefore this name must be unique within its context -
ElastiCache or an Amazon S3 bucket if exporting.

@option params [String] :target_bucket

The Amazon S3 bucket to which the snapshot is exported. This parameter
is used only when exporting a snapshot for external access.

When using this parameter to export a snapshot, be sure Amazon
ElastiCache has the needed permissions to this S3 bucket. For more
information, see [Step 2: Grant ElastiCache Access to Your Amazon S3
Bucket][1] in the *Amazon ElastiCache User Guide*.

For more information, see [Exporting a Snapshot][2] in the *Amazon
ElastiCache User Guide*.

create_cache_cluster(params = {}, options = {}) click to toggle source

Creates a cluster. All nodes in the cluster run the same protocol-compliant cache engine software, either Memcached or Redis.

This operation is not supported for Redis (cluster mode enabled) clusters.

@option params [required, String] :cache_cluster_id

The node group (shard) identifier. This parameter is stored as a
lowercase string.

**Constraints:**

* A name must contain from 1 to 50 alphanumeric characters or hyphens.

* The first character must be a letter.

* A name cannot end with a hyphen or contain two consecutive hyphens.

@option params [String] :replication_group_id

The ID of the replication group to which this cluster should belong.
If this parameter is specified, the cluster is added to the specified
replication group as a read replica; otherwise, the cluster is a
standalone primary that is not part of any replication group.

If the specified replication group is Multi-AZ enabled and the
Availability Zone is not specified, the cluster is created in
Availability Zones that provide the best spread of read replicas
across Availability Zones.

<note markdown="1"> This parameter is only valid if the `Engine` parameter is `redis`.

 </note>

@option params [String] :az_mode

Specifies whether the nodes in this Memcached cluster are created in a
single Availability Zone or created across multiple Availability Zones
in the cluster's region.

This parameter is only supported for Memcached clusters.

If the `AZMode` and `PreferredAvailabilityZones` are not specified,
ElastiCache assumes `single-az` mode.

@option params [String] :preferred_availability_zone

The EC2 Availability Zone in which the cluster is created.

All nodes belonging to this cluster are placed in the preferred
Availability Zone. If you want to create your nodes across multiple
Availability Zones, use `PreferredAvailabilityZones`.

Default: System chosen Availability Zone.

@option params [Array<String>] :preferred_availability_zones

A list of the Availability Zones in which cache nodes are created. The
order of the zones in the list is not important.

This option is only supported on Memcached.

<note markdown="1"> If you are creating your cluster in an Amazon VPC (recommended) you
can only locate nodes in Availability Zones that are associated with
the subnets in the selected subnet group.

 The number of Availability Zones listed must equal the value of
`NumCacheNodes`.

 </note>

If you want all the nodes in the same Availability Zone, use
`PreferredAvailabilityZone` instead, or repeat the Availability Zone
multiple times in the list.

Default: System chosen Availability Zones.

@option params [Integer] :num_cache_nodes

The initial number of cache nodes that the cluster has.

For clusters running Redis, this value must be 1. For clusters running
Memcached, this value must be between 1 and 40.

If you need more than 40 nodes for your Memcached cluster, please fill
out the ElastiCache Limit Increase Request form at
[http://aws.amazon.com/contact-us/elasticache-node-limit-request/][1].

Global Datastore for Redis offers fully managed, fast, reliable and secure cross-region replication. Using Global Datastore for Redis, you can create cross-region read replica clusters for ElastiCache for Redis to enable low-latency reads and disaster recovery across regions. For more information, see [Replication Across Regions Using Global Datastore].

  • The GlobalReplicationGroupIdSuffix is the name of the Global datastore.

  • The PrimaryReplicationGroupId represents the name of the primary cluster that accepts writes and will replicate updates to the secondary cluster.

[1]: docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Redis-Global-Datastore.html

@option params [required, String] :global_replication_group_id_suffix

The suffix name of a Global datastore. Amazon ElastiCache
automatically applies a prefix to the Global datastore ID when it is
created. Each Amazon Region has its own prefix. For instance, a Global
datastore ID created in the US-West-1 region will begin with "dsdfu"
along with the suffix name you provide. The suffix, combined with the
auto-generated prefix, guarantees uniqueness of the Global datastore
name across multiple regions.

For a full list of Amazon Regions and their respective Global
datastore iD prefixes, see [Using the Amazon CLI with Global
datastores ][1].

create_replication_group(params = {}, options = {}) click to toggle source

Creates a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group.

This API can be used to create a standalone regional replication group or a secondary replication group associated with a Global datastore.

A Redis (cluster mode disabled) replication group is a collection of clusters, where one of the clusters is a read/write primary and the others are read-only replicas. Writes to the primary are asynchronously propagated to the replicas.

A Redis cluster-mode enabled cluster is comprised of from 1 to 90 shards (API/CLI: node groups). Each shard has a primary node and up to 5 read-only replica nodes. The configuration can range from 90 shards and 0 replicas to 15 shards and 5 replicas, which is the maximum number or replicas allowed.

The node or shard limit can be increased to a maximum of 500 per cluster if the Redis engine version is 5.0.6 or higher. For example, you can choose to configure a 500 node cluster that ranges between 83 shards (one primary and 5 replicas per shard) and 500 shards (single primary and no replicas). Make sure there are enough available IP addresses to accommodate the increase. Common pitfalls include the subnets in the subnet group have too small a CIDR range or the subnets are shared and heavily used by other clusters. For more information, see [Creating a Subnet Group]. For versions below 5.0.6, the limit is 250 per cluster.

To request a limit increase, see [Amazon Service Limits] and choose the limit type **Nodes per cluster per instance type**.

When a Redis (cluster mode disabled) replication group has been successfully created, you can add one or more read replicas to it, up to a total of 5 read replicas. If you need to increase or decrease the number of node groups (console: shards), you can avail yourself of ElastiCache for Redis' scaling. For more information, see [Scaling ElastiCache for Redis Clusters] in the *ElastiCache User Guide*.

<note markdown=“1”> This operation is valid for Redis only.

@option params [required, String] :replication_group_id

The replication group identifier. This parameter is stored as a
lowercase string.

Constraints:

* A name must contain from 1 to 40 alphanumeric characters or hyphens.

* The first character must be a letter.

* A name cannot end with a hyphen or contain two consecutive hyphens.

@option params [required, String] :replication_group_description

A user-created description for the replication group.

@option params [String] :global_replication_group_id

The name of the Global datastore

@option params [String] :primary_cluster_id

The identifier of the cluster that serves as the primary for this
replication group. This cluster must already exist and have a status
of `available`.

This parameter is not required if `NumCacheClusters`, `NumNodeGroups`,
or `ReplicasPerNodeGroup` is specified.

@option params [Boolean] :automatic_failover_enabled

Specifies whether a read-only replica is automatically promoted to
read/write primary if the existing primary fails.

`AutomaticFailoverEnabled` must be enabled for Redis (cluster mode
enabled) replication groups.

Default: false

@option params [Boolean] :multi_az_enabled

A flag indicating if you have Multi-AZ enabled to enhance fault
tolerance. For more information, see [Minimizing Downtime:
Multi-AZ][1].

[1]: http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/AutoFailover.html

@option params [Integer] :num_cache_clusters

The number of clusters this replication group initially has.

This parameter is not used if there is more than one node group
(shard). You should use `ReplicasPerNodeGroup` instead.

If `AutomaticFailoverEnabled` is `true`, the value of this parameter
must be at least 2. If `AutomaticFailoverEnabled` is `false` you can
omit this parameter (it will default to 1), or you can explicitly set
it to a value between 2 and 6.

The maximum permitted value for `NumCacheClusters` is 6 (1 primary
plus 5 replicas).

@option params [Array<String>] :preferred_cache_cluster_a_zs

A list of EC2 Availability Zones in which the replication group's
clusters are created. The order of the Availability Zones in the list
is the order in which clusters are allocated. The primary cluster is
created in the first AZ in the list.

This parameter is not used if there is more than one node group
(shard). You should use `NodeGroupConfiguration` instead.

<note markdown="1"> If you are creating your replication group in an Amazon VPC
(recommended), you can only locate clusters in Availability Zones
associated with the subnets in the selected subnet group.

 The number of Availability Zones listed must equal the value of
`NumCacheClusters`.

 </note>

Default: system chosen Availability Zones.

@option params [Integer] :num_node_groups

An optional parameter that specifies the number of node groups
(shards) for this Redis (cluster mode enabled) replication group. For
Redis (cluster mode disabled) either omit this parameter or set it to
1.

Default: 1

@option params [Integer] :replicas_per_node_group

An optional parameter that specifies the number of replica nodes in
each node group (shard). Valid values are 0 to 5.

@option params [Array<Types::NodeGroupConfiguration>] :node_group_configuration

A list of node group (shard) configuration options. Each node group
(shard) configuration has the following members:
`PrimaryAvailabilityZone`, `ReplicaAvailabilityZones`, `ReplicaCount`,
and `Slots`.

If you're creating a Redis (cluster mode disabled) or a Redis
(cluster mode enabled) replication group, you can use this parameter
to individually configure each node group (shard), or you can omit
this parameter. However, it is required when seeding a Redis (cluster
mode enabled) cluster from a S3 rdb file. You must configure each node
group (shard) using this parameter because you must specify the slots
for each node group.

@option params [String] :cache_node_type

The compute and memory capacity of the nodes in the node group
(shard).

The following node types are supported by ElastiCache. Generally
speaking, the current generation types provide more memory and
computational power at lower cost when compared to their equivalent
previous generation counterparts.

* General purpose:

  * Current generation:

    **M6g node types** (available only for Redis engine version 5.0.6
    onward and for Memcached engine version 1.5.16 onward).

    `cache.m6g.large`, `cache.m6g.xlarge`, `cache.m6g.2xlarge`,
    `cache.m6g.4xlarge`, `cache.m6g.8xlarge`, `cache.m6g.12xlarge`,
    `cache.m6g.16xlarge`

    <note markdown="1"> For region availability, see [Supported Node Types][1]

     </note>

    **M5 node types:** `cache.m5.large`, `cache.m5.xlarge`,
    `cache.m5.2xlarge`, `cache.m5.4xlarge`, `cache.m5.12xlarge`,

@option params [String] :engine

The name of the cache engine to be used for the clusters in this
replication group. Must be Redis.

@option params [String] :engine_version

The version number of the cache engine to be used for the clusters in
this replication group. To view the supported cache engine versions,
use the `DescribeCacheEngineVersions` operation.

**Important:** You can upgrade to a newer engine version (see
[Selecting a Cache Engine and Version][1]) in the *ElastiCache User
Guide*, but you cannot downgrade to an earlier engine version. If you
want to use an earlier engine version, you must delete the existing
cluster or replication group and create it anew with the earlier
engine version.

[1]: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/SelectEngine.html#VersionManagement

@option params [String] :cache_parameter_group_name

The name of the parameter group to associate with this replication
group. If this argument is omitted, the default cache parameter group
for the specified engine is used.

If you are running Redis version 3.2.4 or later, only one node group
(shard), and want to use a default parameter group, we recommend that
you specify the parameter group by name.

* To create a Redis (cluster mode disabled) replication group, use
  `CacheParameterGroupName=default.redis3.2`.

* To create a Redis (cluster mode enabled) replication group, use
  `CacheParameterGroupName=default.redis3.2.cluster.on`.

@option params [String] :cache_subnet_group_name

The name of the cache subnet group to be used for the replication
group.

If you're going to launch your cluster in an Amazon VPC, you need to
create a subnet group before you start creating a cluster. For more
information, see [Subnets and Subnet Groups][1].

[1]: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/SubnetGroups.html

@option params [Array<String>] :cache_security_group_names

A list of cache security group names to associate with this
replication group.

@option params [Array<String>] :security_group_ids

One or more Amazon VPC security groups associated with this
replication group.

Use this parameter only when you are creating a replication group in
an Amazon Virtual Private Cloud (Amazon VPC).

@option params [Array<Types::Tag>] :tags

A list of tags to be added to this resource. Tags are comma-separated
key,value pairs (e.g. Key=`myKey`, Value=`myKeyValue`. You can include
multiple tags as shown following: Key=`myKey`, Value=`myKeyValue`
Key=`mySecondKey`, Value=`mySecondKeyValue`. Tags on replication
groups will be replicated to all nodes.

@option params [Array<String>] :snapshot_arns

A list of Amazon Resource Names (ARN) that uniquely identify the Redis
RDB snapshot files stored in Amazon S3. The snapshot files are used to
populate the new replication group. The Amazon S3 object name in the
ARN cannot contain any commas. The new replication group will have the
number of node groups (console: shards) specified by the parameter
*NumNodeGroups* or the number of node groups configured by
*NodeGroupConfiguration* regardless of the number of ARNs specified
here.

Example of an Amazon S3 ARN: `arn:aws:s3:::my_bucket/snapshot1.rdb`

@option params [String] :snapshot_name

The name of a snapshot from which to restore data into the new
replication group. The snapshot status changes to `restoring` while
the new replication group is being created.

@option params [String] :preferred_maintenance_window

Specifies the weekly time range during which maintenance on the
cluster is performed. It is specified as a range in the format
ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance
window is a 60 minute period. Valid values for `ddd` are:

Specifies the weekly time range during which maintenance on the
cluster is performed. It is specified as a range in the format
ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance
window is a 60 minute period.

Valid values for `ddd` are:

* `sun`

* `mon`

* `tue`

* `wed`

* `thu`

* `fri`

* `sat`

Example: `sun:23:00-mon:01:30`

@option params [Integer] :port

The port number on which each member of the replication group accepts
connections.

@option params [String] :notification_topic_arn

The Amazon Resource Name (ARN) of the Amazon Simple Notification
Service (SNS) topic to which notifications are sent.

<note markdown="1"> The Amazon SNS topic owner must be the same as the cluster owner.

 </note>

@option params [Boolean] :auto_minor_version_upgrade

This parameter is currently disabled.

@option params [Integer] :snapshot_retention_limit

The number of days for which ElastiCache retains automatic snapshots
before deleting them. For example, if you set `SnapshotRetentionLimit`
to 5, a snapshot that was taken today is retained for 5 days before
being deleted.

Default: 0 (i.e., automatic backups are disabled for this cluster).

@option params [String] :snapshot_window

The daily time range (in UTC) during which ElastiCache begins taking a
daily snapshot of your node group (shard).

Example: `05:00-09:00`

If you do not specify this parameter, ElastiCache automatically
chooses an appropriate time range.

@option params [String] :auth_token

**Reserved parameter.** The password used to access a password
protected server.

`AuthToken` can be specified only on replication groups where
`TransitEncryptionEnabled` is `true`.

For HIPAA compliance, you must specify `TransitEncryptionEnabled` as
`true`, an `AuthToken`, and a `CacheSubnetGroup`.

Password constraints:

* Must be only printable ASCII characters.

* Must be at least 16 characters and no more than 128 characters in
  length.

* The only permitted printable special characters are !, &amp;, #, $,
  ^, &lt;, &gt;, and -. Other printable special characters cannot be
  used in the AUTH token.

For more information, see [AUTH password][1] at
http://redis.io/commands/AUTH.

[1]: http://redis.io/commands/AUTH

@option params [Boolean] :transit_encryption_enabled

A flag that enables in-transit encryption when set to `true`.

You cannot modify the value of `TransitEncryptionEnabled` after the
cluster is created. To enable in-transit encryption on a cluster you
must set `TransitEncryptionEnabled` to `true` when you create a
cluster.

This parameter is valid only if the `Engine` parameter is `redis`, the
`EngineVersion` parameter is `3.2.6`, `4.x` or later, and the cluster
is being created in an Amazon VPC.

If you enable in-transit encryption, you must also specify a value for
`CacheSubnetGroup`.

**Required:** Only available when creating a replication group in an
Amazon VPC using redis version `3.2.6`, `4.x` or later.

Default: `false`

For HIPAA compliance, you must specify `TransitEncryptionEnabled` as
`true`, an `AuthToken`, and a `CacheSubnetGroup`.

@option params [Boolean] :at_rest_encryption_enabled

A flag that enables encryption at rest when set to `true`.

You cannot modify the value of `AtRestEncryptionEnabled` after the
replication group is created. To enable encryption at rest on a
replication group you must set `AtRestEncryptionEnabled` to `true`
when you create the replication group.

**Required:** Only available when creating a replication group in an
Amazon VPC using redis version `3.2.6`, `4.x` or later.

Default: `false`

@option params [String] :kms_key_id

The ID of the KMS key used to encrypt the disk in the cluster.

The user group to associate with the replication group.

@option params [Array<Types::LogDeliveryConfigurationRequest>] :log_delivery_configurations

Specifies the destination, format and type of the logs.

@return [Types::CreateReplicationGroupResult] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::CreateReplicationGroupResult#replication_group #replication_group} => Types::ReplicationGroup

@example Example: CreateCacheReplicationGroup

decrease_replica_count(params = {}, options = {}) click to toggle source

Dynamically decreases the number of replicas in a Redis (cluster mode disabled) replication group or the number of replica nodes in one or more node groups (shards) of a Redis (cluster mode enabled) replication group. This operation is performed with no cluster down time.

@option params [required, String] :replication_group_id

The id of the replication group from which you want to remove replica
nodes.

@option params [Integer] :new_replica_count

The number of read replica nodes you want at the completion of this
operation. For Redis (cluster mode disabled) replication groups, this
is the number of replica nodes in the replication group. For Redis
(cluster mode enabled) replication groups, this is the number of
replica nodes in each of the replication group's node groups.

The minimum number of replicas in a shard or replication group is:

* Redis (cluster mode disabled)

  * If Multi-AZ is enabled: 1

  * If Multi-AZ is not enabled: 0

* Redis (cluster mode enabled): 0 (though you will not be able to
  failover to a replica if your primary node fails)

@option params [Array<Types::ConfigureShard>] :replica_configuration

A list of `ConfigureShard` objects that can be used to configure each
shard in a Redis (cluster mode enabled) replication group. The
`ConfigureShard` has three members: `NewReplicaCount`, `NodeGroupId`,
and `PreferredAvailabilityZones`.

@option params [Array<String>] :replicas_to_remove

A list of the node ids to remove from the replication group or node
group (shard).

@option params [required, Boolean] :apply_immediately

If `True`, the number of replica nodes is decreased immediately.
`ApplyImmediately=False` is not currently supported.

@return [Types::DecreaseReplicaCountResult] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::DecreaseReplicaCountResult#replication_group #replication_group} => Types::ReplicationGroup

delete_cache_cluster(params = {}, options = {}) click to toggle source

Deletes a previously provisioned cluster. `DeleteCacheCluster` deletes all associated cache nodes, node endpoints and the cluster itself. When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the cluster; you cannot cancel or revert this operation.

This operation is not valid for:

  • Redis (cluster mode enabled) clusters

  • Redis (cluster mode disabled) clusters

  • A cluster that is the last read replica of a replication group

  • A cluster that is the primary node of a replication group

  • A node group (shard) that has Multi-AZ mode enabled

  • A cluster from a Redis (cluster mode enabled) replication group

  • A cluster that is not in the `available` state

@option params [required, String] :cache_cluster_id

The cluster identifier for the cluster to be deleted. This parameter
is not case sensitive.

@option params [String] :final_snapshot_identifier

The user-supplied name of a final cluster snapshot. This is the unique
name that identifies the snapshot. ElastiCache creates the snapshot,
and then deletes the cluster immediately afterward.

@return [Types::DeleteCacheClusterResult] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::DeleteCacheClusterResult#cache_cluster #cache_cluster} => Types::CacheCluster

@example Example: DeleteCacheCluster

delete_global_replication_group(params = {}, options = {}) click to toggle source

Deleting a Global datastore is a two-step process:

  • First, you must DisassociateGlobalReplicationGroup to remove the secondary clusters in the Global datastore.

  • Once the Global datastore contains only the primary cluster, you can use the `DeleteGlobalReplicationGroup` API to delete the Global datastore while retainining the primary cluster using `RetainPrimaryReplicationGroup=true`.

Since the Global Datastore has only a primary cluster, you can delete the Global Datastore while retaining the primary by setting `RetainPrimaryReplicationGroup=true`. The primary cluster is never deleted when deleting a Global Datastore. It can only be deleted when it no longer is associated with any Global Datastore.

When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.

@option params [required, String] :global_replication_group_id

The name of the Global datastore

@option params [required, Boolean] :retain_primary_replication_group

The primary replication group is retained as a standalone replication
group.

@return [Types::DeleteGlobalReplicationGroupResult] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

delete_replication_group(params = {}, options = {}) click to toggle source

Deletes an existing replication group. By default, this operation deletes the entire replication group, including the primary/primaries and all of the read replicas. If the replication group has only one primary, you can optionally delete only the read replicas, while retaining the primary by setting `RetainPrimaryCluster=true`.

When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.

<note markdown=“1”> This operation is valid for Redis only.

</note>

@option params [required, String] :replication_group_id

The identifier for the cluster to be deleted. This parameter is not
case sensitive.

@option params [Boolean] :retain_primary_cluster

If set to `true`, all of the read replicas are deleted, but the
primary node is retained.

@option params [String] :final_snapshot_identifier

The name of a final node group (shard) snapshot. ElastiCache creates
the snapshot from the primary node in the cluster, rather than one of
the replicas; this is to ensure that it captures the freshest data.
After the final snapshot is taken, the replication group is
immediately deleted.

@return [Types::DeleteReplicationGroupResult] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::DeleteReplicationGroupResult#replication_group #replication_group} => Types::ReplicationGroup

@example Example: DeleteReplicationGroup

Returns information about all provisioned clusters if no cluster identifier is specified, or about a specific cache cluster if a cluster identifier is supplied.

By default, abbreviated information about the clusters is returned. You can use the optional ShowCacheNodeInfo flag to retrieve detailed information about the cache nodes associated with the clusters. These details include the DNS address and port for the cache node endpoint.

If the cluster is in the creating state, only cluster-level information is displayed until all of the nodes are successfully provisioned.

If the cluster is in the deleting state, only cluster-level information is displayed.

If cache nodes are currently being added to the cluster, node endpoint information and creation time for the additional nodes are not displayed until they are completely provisioned. When the cluster state is available, the cluster is ready for use.

If cache nodes are currently being removed from the cluster, no endpoint information for the removed nodes is displayed.

The user-supplied cluster identifier. If this parameter is specified,
only information about that specific cluster is returned. This
parameter isn't case sensitive.

@option params [Integer] :max_records

The maximum number of records to include in the response. If more
records exist than the specified `MaxRecords` value, a marker is
included in the response so that the remaining results can be
retrieved.

Default: 100

Constraints: minimum 20; maximum 100.

@option params [String] :marker

An optional marker returned from a prior request. Use this marker for
pagination of results from this operation. If this parameter is
specified, the response includes only records beyond the marker, up to
the value specified by `MaxRecords`.

@option params [Boolean] :show_cache_node_info

An optional flag that can be included in the `DescribeCacheCluster`
request to retrieve information about the individual cache nodes.

@option params [Boolean] :show_cache_clusters_not_in_replication_groups

An optional flag that can be included in the `DescribeCacheCluster`
request to show only nodes (API/CLI: clusters) that are not members of
a replication group. In practice, this mean Memcached and single node
Redis clusters.

@return [Types::CacheClusterMessage] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::CacheClusterMessage#marker #marker} => String
* {Types::CacheClusterMessage#cache_clusters #cache_clusters} => Array&lt;Types::CacheCluster&gt;

The returned {Seahorse::Client::Response response} is a pageable response and is Enumerable. For details on usage see {Aws::PageableResponse PageableResponse}.

Returns the detailed parameter list for a particular cache parameter group.

@option params [required, String] :cache_parameter_group_name

The name of a specific cache parameter group to return details for.

@option params [String] :source

The parameter types to return.

Valid values: `user` \| `system` \| `engine-default`

@option params [Integer] :max_records

The maximum number of records to include in the response. If more
records exist than the specified `MaxRecords` value, a marker is
included in the response so that the remaining results can be
retrieved.

Default: 100

Constraints: minimum 20; maximum 100.

@option params [String] :marker

An optional marker returned from a prior request. Use this marker for
pagination of results from this operation. If this parameter is
specified, the response includes only records beyond the marker, up to
the value specified by `MaxRecords`.

@return [Types::CacheParameterGroupDetails] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::CacheParameterGroupDetails#marker #marker} => String
* {Types::CacheParameterGroupDetails#parameters #parameters} => Array&lt;Types::Parameter&gt;
* {Types::CacheParameterGroupDetails#cache_node_type_specific_parameters #cache_node_type_specific_parameters} => Array&lt;Types::CacheNodeTypeSpecificParameter&gt;

The returned {Seahorse::Client::Response response} is a pageable response and is Enumerable. For details on usage see {Aws::PageableResponse PageableResponse}.

@example Example: DescribeCacheParameters

# Lists up to 100 user parameter values for the parameter group custom.redis2.8.

describe_cache_subnet_groups(params = {}, options = {}) click to toggle source

Returns a list of cache subnet group descriptions. If a subnet group name is specified, the list contains only the description of that group. This is applicable only when you have ElastiCache in VPC setup. All ElastiCache clusters now launch in VPC by default.

@option params [String] :cache_subnet_group_name

The name of the cache subnet group to return details for.

@option params [Integer] :max_records

The maximum number of records to include in the response. If more
records exist than the specified `MaxRecords` value, a marker is
included in the response so that the remaining results can be
retrieved.

Default: 100

Constraints: minimum 20; maximum 100.

@option params [String] :marker

An optional marker returned from a prior request. Use this marker for
pagination of results from this operation. If this parameter is
specified, the response includes only records beyond the marker, up to
the value specified by `MaxRecords`.

@return [Types::CacheSubnetGroupMessage] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::CacheSubnetGroupMessage#marker #marker} => String
* {Types::CacheSubnetGroupMessage#cache_subnet_groups #cache_subnet_groups} => Array&lt;Types::CacheSubnetGroup&gt;

The returned {Seahorse::Client::Response response} is a pageable response and is Enumerable. For details on usage see {Aws::PageableResponse PageableResponse}.

@example Example: DescribeCacheSubnetGroups

# Describes up to 25 cache subnet groups.

resp = client.describe_cache_subnet_groups({
  max_records: 25,

describe_events(params = {}, options = {}) click to toggle source

Returns events related to clusters, cache security groups, and cache parameter groups. You can obtain events specific to a particular cluster, cache security group, or cache parameter group by providing the name as a parameter.

By default, only the events occurring within the last hour are returned; however, you can retrieve up to 14 days' worth of events if necessary.

@option params [String] :source_identifier

The identifier of the event source for which events are returned. If
not specified, all sources are included in the response.

@option params [String] :source_type

The event source to retrieve events for. If no value is specified, all
events are returned.

@option params [Time,DateTime,Date,Integer,String] :start_time

The beginning of the time interval to retrieve events for, specified
in ISO 8601 format.

**Example:** 2017-03-30T07:03:49.555Z

@option params [Time,DateTime,Date,Integer,String] :end_time

The end of the time interval for which to retrieve events, specified
in ISO 8601 format.

**Example:** 2017-03-30T07:03:49.555Z

@option params [Integer] :duration

The number of minutes worth of events to retrieve.

@option params [Integer] :max_records

The maximum number of records to include in the response. If more
records exist than the specified `MaxRecords` value, a marker is
included in the response so that the remaining results can be
retrieved.

Default: 100

Constraints: minimum 20; maximum 100.

@option params [String] :marker

An optional marker returned from a prior request. Use this marker for
pagination of results from this operation. If this parameter is
specified, the response includes only records beyond the marker, up to
the value specified by `MaxRecords`.

@return [Types::EventsMessage] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::EventsMessage#marker #marker} => String
* {Types::EventsMessage#events #events} => Array&lt;Types::Event&gt;

The returned {Seahorse::Client::Response response} is a pageable response and is Enumerable. For details on usage see {Aws::PageableResponse PageableResponse}.

Duration filter value, specified in years or seconds. Use this
parameter to show only reservations for a given duration.

Valid Values: `1 | 3 | 31536000 | 94608000`

@option params [String] :product_description

The product description filter value. Use this parameter to show only
the available offerings matching the specified product description.

@option params [String] :offering_type

The offering type filter value. Use this parameter to show only the
available offerings matching the specified offering type.

Valid Values: `"Light Utilization"|"Medium Utilization"|"Heavy
Utilization" |"All Upfront"|"Partial Upfront"| "No Upfront"`

@option params [Integer] :max_records

The maximum number of records to include in the response. If more
records exist than the specified `MaxRecords` value, a marker is
included in the response so that the remaining results can be
retrieved.

Default: 100

Constraints: minimum 20; maximum 100.

@option params [String] :marker

An optional marker returned from a prior request. Use this marker for
pagination of results from this operation. If this parameter is
specified, the response includes only records beyond the marker, up to
the value specified by `MaxRecords`.

@return [Types::ReservedCacheNodesOfferingMessage] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

* {Types::ReservedCacheNodesOfferingMessage#marker #marker} => String
* {Types::ReservedCacheNodesOfferingMessage#reserved_cache_nodes_offerings #reserved_cache_nodes_offerings} => Array&lt;Types::ReservedCacheNodesOffering&gt;

The returned {Seahorse::Client::Response response} is a pageable response and is Enumerable. For details on usage see {Aws::PageableResponse PageableResponse}.

describe_snapshots(params = {}, options = {}) click to toggle source

Returns information about cluster or replication group snapshots. By default, `DescribeSnapshots` lists all of your snapshots; it can optionally describe a single snapshot, or just the snapshots associated with a particular cache cluster.

<note markdown=“1”> This operation is valid for Redis only.

</note>

@option params [String] :replication_group_id

A user-supplied replication group identifier. If this parameter is
specified, only snapshots associated with that specific replication
group are described.

@option params [String] :cache_cluster_id

A user-supplied cluster identifier. If this parameter is specified,
only snapshots associated with that specific cluster are described.

@option params [String] :snapshot_name

A user-supplied name of the snapshot. If this parameter is specified,
only this snapshot are described.

@option params [String] :snapshot_source

If set to `system`, the output shows snapshots that were automatically
created by ElastiCache. If set to `user` the output shows snapshots
that were manually created. If omitted, the output shows both
automatically and manually created snapshots.

@option params [String] :marker

An optional marker returned from a prior request. Use this marker for
pagination of results from this operation. If this parameter is
specified, the response includes only records beyond the marker, up to
the value specified by `MaxRecords`.

@option params [Integer] :max_records

The maximum number of records to include in the response. If more
records exist than the specified `MaxRecords` value, a marker is
included in the response so that the remaining results can be
retrieved.

Default: 50

Constraints: minimum 20; maximum 50.

@option params [Boolean] :show_node_group_config

A Boolean value which if true, the node group (shard) configuration is
included in the snapshot description.

list_allowed_node_type_modifications(params = {}, options = {}) click to toggle source

Lists all available node types that you can scale your Redis cluster's or replication group's current node type.

When you use the `ModifyCacheCluster` or `ModifyReplicationGroup` operations to scale your cluster or replication group, the value of the `CacheNodeType` parameter must be one of the node types returned by this operation.

@option params [String] :cache_cluster_id

The name of the cluster you want to scale up to a larger node
instanced type. ElastiCache uses the cluster id to identify the
current node type of this cluster and from that to create a list of
node types you can scale up to.

You must provide a value for either the `CacheClusterId` or the
`ReplicationGroupId`.

@option params [String] :replication_group_id

The name of the replication group want to scale up to a larger node
type. ElastiCache uses the replication group id to identify the
current node type being used by this replication group, and from that
to create a list of node types you can scale up to.

You must provide a value for either the `CacheClusterId` or the
`ReplicationGroupId`.

@return [Types::AllowedNodeTypeModificationsMessage] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

list_tags_for_resource(params = {}, options = {}) click to toggle source

Lists all tags currently on a named resource.

A tag is a key-value pair where the key and value are case-sensitive. You can use tags to categorize and track all your ElastiCache resources, with the exception of global replication group. When you add or remove tags on replication groups, those actions will be replicated to all nodes in the replication group. For more information, see [Resource-level permissions].

If the cluster is not in the available state, `ListTagsForResource` returns an error.

[1]: docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/IAM.ResourceLevelPermissions.html

@option params [required, String] :resource_name

The Amazon Resource Name (ARN) of the resource for which you want the
list of tags, for example
`arn:aws:elasticache:us-west-2:0123456789:cluster:myCluster` or
`arn:aws:elasticache:us-west-2:0123456789:snapshot:mySnapshot`.

modify_cache_cluster(params = {}, options = {}) click to toggle source

Modifies the settings for a cluster. You can use this operation to change one or more cluster configuration parameters by specifying the parameters and the new values.

@option params [required, String] :cache_cluster_id

The cluster identifier. This value is stored as a lowercase string.

@option params [Integer] :num_cache_nodes

The number of cache nodes that the cluster should have. If the value
for `NumCacheNodes` is greater than the sum of the number of current
cache nodes and the number of cache nodes pending creation (which may
be zero), more nodes are added. If the value is less than the number
of existing cache nodes, nodes are removed. If the value is equal to
the number of current cache nodes, any pending add or remove requests
are canceled.

If you are removing cache nodes, you must use the
`CacheNodeIdsToRemove` parameter to provide the IDs of the specific
cache nodes to remove.

For clusters running Redis, this value must be 1. For clusters running
Memcached, this value must be between 1 and 40.

<note markdown="1"> Adding or removing Memcached cache nodes can be applied immediately or
as a pending operation (see `ApplyImmediately`).

 A pending operation to modify the number of cache nodes in a cluster
during its maintenance window, whether by adding or removing nodes in
accordance with the scale out architecture, is not queued. The
customer's latest request to add or remove nodes to the cluster
overrides any previous pending operations to modify the number of
cache nodes in the cluster. For example, a request to remove 2 nodes
would override a previous pending operation to remove 3 nodes.
Similarly, a request to add 2 nodes would override a previous pending
operation to remove 3 nodes and vice versa. As Memcached cache nodes
may now be provisioned in different Availability Zones with flexible
cache node placement, a request to add nodes does not automatically
override a previous pending operation to add nodes. The customer can
modify the previous pending operation to add more nodes or explicitly
cancel the pending request and retry the new request. To cancel
pending operations to modify the number of cache nodes in a cluster,
use the `ModifyCacheCluster` request and set `NumCacheNodes` equal to
the number of cache nodes currently in the cluster.

 </note>

@option params [Array<String>] :cache_node_ids_to_remove

A list of cache node IDs to be removed. A node ID is a numeric
identifier (0001, 0002, etc.). This parameter is only valid when
`NumCacheNodes` is less than the existing number of cache nodes. The
number of cache node IDs supplied in this parameter must match the
difference between the existing number of cache nodes in the cluster
or pending cache nodes, whichever is greater, and the value of
`NumCacheNodes` in the request.

For example: If you have 3 active cache nodes, 7 pending cache nodes,
and the number of cache nodes in this `ModifyCacheCluster` call is 5,
you must list 2 (7 - 5) cache node IDs to remove.

@option params [String] :az_mode

Specifies whether the new nodes in this Memcached cluster are all
created in a single Availability Zone or created across multiple
Availability Zones.

Valid values: `single-az` \| `cross-az`.

This option is only supported for Memcached clusters.

<note markdown="1"> You cannot specify `single-az` if the Memcached cluster already has
cache nodes in different Availability Zones. If `cross-az` is
specified, existing Memcached nodes remain in their current
Availability Zone.

 Only newly created nodes are located in different Availability Zones.

 </note>

@option params [Array<String>] :new_availability_zones

<note markdown="1"> This option is only supported on Memcached clusters.

 </note>

The list of Availability Zones where the new Memcached cache nodes are
created.

This parameter is only valid when `NumCacheNodes` in the request is
greater than the sum of the number of active cache nodes and the
number of cache nodes pending creation (which may be zero). The number
of Availability Zones supplied in this list must match the cache nodes
being added in this request.

Scenarios:

* **Scenario 1:** You have 3 active nodes and wish to add 2 nodes.
  Specify `NumCacheNodes=5` (3 + 2) and optionally specify two
  Availability Zones for the two new nodes.

* **Scenario 2:** You have 3 active nodes and 2 nodes pending creation
  (from the scenario 1 call) and want to add 1 more node. Specify
  `NumCacheNodes=6` ((3 + 2) + 1) and optionally specify an
  Availability Zone for the new node.

* **Scenario 3:** You want to cancel all pending operations. Specify
  `NumCacheNodes=3` to cancel all pending operations.

The Availability Zone placement of nodes pending creation cannot be
modified. If you wish to cancel any nodes pending creation, add 0
nodes by setting `NumCacheNodes` to the number of current nodes.

If `cross-az` is specified, existing Memcached nodes remain in their
current Availability Zone. Only newly created nodes can be located in
different Availability Zones. For guidance on how to move existing
Memcached nodes to different Availability Zones, see the
**Availability Zone Considerations** section of [Cache Node
Considerations for Memcached][1].

**Impact of new add/remove requests upon pending requests**

* Scenario-1

  * Pending Action: Delete

  * New Request: Delete

  * Result: The new delete, pending or immediate, replaces the pending
    delete.

* Scenario-2

  * Pending Action: Delete

  * New Request: Create

  * Result: The new create, pending or immediate, replaces the pending
    delete.

* Scenario-3

  * Pending Action: Create

  * New Request: Delete

  * Result: The new delete, pending or immediate, replaces the pending
    create.

* Scenario-4

  * Pending Action: Create

  * New Request: Create

  * Result: The new create is added to the pending create.

    **Important:** If the new create request is **Apply Immediately -
    Yes**, all creates are performed immediately. If the new create
    request is **Apply Immediately - No**, all creates are pending.

@option params [Array<String>] :cache_security_group_names

A list of cache security group names to authorize on this cluster.
This change is asynchronously applied as soon as possible.

You can use this parameter only with clusters that are created outside
of an Amazon Virtual Private Cloud (Amazon VPC).

Constraints: Must contain no more than 255 alphanumeric characters.
Must not be "Default".

@option params [Array<String>] :security_group_ids

Specifies the VPC Security Groups associated with the cluster.

This parameter can be used only with clusters that are created in an
Amazon Virtual Private Cloud (Amazon VPC).

@option params [String] :preferred_maintenance_window

Specifies the weekly time range during which maintenance on the
cluster is performed. It is specified as a range in the format
ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance
window is a 60 minute period.

Valid values for `ddd` are:

* `sun`

* `mon`

* `tue`

* `wed`

* `thu`

* `fri`

* `sat`

Example: `sun:23:00-mon:01:30`

@option params [String] :notification_topic_arn

The Amazon Resource Name (ARN) of the Amazon SNS topic to which
notifications are sent.

<note markdown="1"> The Amazon SNS topic owner must be same as the cluster owner.

 </note>

@option params [String] :cache_parameter_group_name

The name of the cache parameter group to apply to this cluster. This
change is asynchronously applied as soon as possible for parameters
when the `ApplyImmediately` parameter is specified as `true` for this
request.

@option params [String] :notification_topic_status

The status of the Amazon SNS notification topic. Notifications are
sent only if the status is `active`.

Valid values: `active` \| `inactive`

@option params [Boolean] :apply_immediately

If `true`, this parameter causes the modifications in this request and
any pending modifications to be applied, asynchronously and as soon as
possible, regardless of the `PreferredMaintenanceWindow` setting for
the cluster.

If `false`, changes to the cluster are applied on the next maintenance
reboot, or the next failure reboot, whichever occurs first.

If you perform a `ModifyCacheCluster` before a pending modification is
applied, the pending modification is replaced by the newer
modification.

Valid values: `true` \| `false`

Default: `false`

@option params [String] :engine_version

The upgraded version of the cache engine to be run on the cache nodes.

**Important:** You can upgrade to a newer engine version (see
[Selecting a Cache Engine and Version][1]), but you cannot downgrade
to an earlier engine version. If you want to use an earlier engine
version, you must delete the existing cluster and create it anew with
the earlier engine version.

[1]: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/SelectEngine.html#VersionManagement

@option params [Boolean] :auto_minor_version_upgrade

This parameter is currently disabled.

@option params [Integer] :snapshot_retention_limit

The number of days for which ElastiCache retains automatic cluster
snapshots before deleting them. For example, if you set
`SnapshotRetentionLimit` to 5, a snapshot that was taken today is
retained for 5 days before being deleted.

<note markdown="1"> If the value of `SnapshotRetentionLimit` is set to zero (0), backups
are turned off.

 </note>

@option params [String] :snapshot_window

The daily time range (in UTC) during which ElastiCache begins taking a
daily snapshot of your cluster.

@option params [String] :cache_node_type

@option params [String] :replication_group_description

A description for the replication group. Maximum length is 255
characters.

@option params [String] :primary_cluster_id

For replication groups with a single primary, if this parameter is
specified, ElastiCache promotes the specified cluster in the specified
replication group to the primary role. The nodes of all other clusters
in the replication group are read replicas.

@option params [String] :snapshotting_cluster_id

The cluster ID that is used as the daily snapshot source for the
replication group. This parameter cannot be set for Redis (cluster
mode enabled) replication groups.

@option params [Boolean] :automatic_failover_enabled

Determines whether a read replica is automatically promoted to
read/write primary if the existing primary encounters a failure.

Valid values: `true` \| `false`

@option params [Boolean] :multi_az_enabled

A flag to indicate MultiAZ is enabled.

@option params [String] :node_group_id

Deprecated. This parameter is not used.

@option params [Array<String>] :cache_security_group_names

A list of cache security group names to authorize for the clusters in
this replication group. This change is asynchronously applied as soon
as possible.

This parameter can be used only with replication group containing
clusters running outside of an Amazon Virtual Private Cloud (Amazon
VPC).

Constraints: Must contain no more than 255 alphanumeric characters.
Must not be `Default`.

@option params [Array<String>] :security_group_ids

Specifies the VPC Security Groups associated with the clusters in the
replication group.

This parameter can be used only with replication group containing
clusters running in an Amazon Virtual Private Cloud (Amazon VPC).

@option params [String] :preferred_maintenance_window

Specifies the weekly time range during which maintenance on the
cluster is performed. It is specified as a range in the format
ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance
window is a 60 minute period.

* `fri`

* `sat`

Example: `sun:23:00-mon:01:30`

@option params [String] :notification_topic_arn

The Amazon Resource Name (ARN) of the Amazon SNS topic to which
notifications are sent.

The status of the Amazon SNS notification topic for the replication
group. Notifications are sent only if the status is `active`.

Valid values: `active` \| `inactive`

@option params [Boolean] :apply_immediately

If `true`, this parameter causes the modifications in this request and
any pending modifications to be applied, asynchronously and as soon as
possible, regardless of the `PreferredMaintenanceWindow` setting for
the replication group.

If `false`, changes to the nodes in the replication group are applied
on the next maintenance reboot, or the next failure reboot, whichever
occurs first.

Valid values: `true` \| `false`

Default: `false`

@option params [String] :engine_version

The upgraded version of the cache engine to be run on the clusters in
the replication group.

**Important:** You can upgrade to a newer engine version (see
[Selecting a Cache Engine and Version][1]), but you cannot downgrade
to an earlier engine version. If you want to use an earlier engine
version, you must delete the existing replication group and create it
anew with the earlier engine version.

[1]: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/SelectEngine.html#VersionManagement

@option params [Boolean] :auto_minor_version_upgrade

This parameter is currently disabled.

@option params [Integer] :snapshot_retention_limit

The number of days for which ElastiCache retains automatic node group
(shard) snapshots before deleting them. For example, if you set
`SnapshotRetentionLimit` to 5, a snapshot that was taken today is
retained for 5 days before being deleted.

**Important** If the value of SnapshotRetentionLimit is set to zero
(0), backups are turned off.

@option params [String] :snapshot_window

The daily time range (in UTC) during which ElastiCache begins taking a
daily snapshot of the node group (shard) specified by
`SnapshottingClusterId`.

Example: `05:00-09:00`

If you do not specify this parameter, ElastiCache automatically
chooses an appropriate time range.

@option params [String] :cache_node_type

modify_replication_group_shard_configuration(params = {}, options = {}) click to toggle source

Modifies a replication group's shards (node groups) by allowing you to add shards, remove shards, or rebalance the keyspaces among existing shards.

@option params [required, String] :replication_group_id

The name of the Redis (cluster mode enabled) cluster (replication
group) on which the shards are to be configured.

@option params [required, Integer] :node_group_count

The number of node groups (shards) that results from the modification
of the shard configuration.

@option params [required, Boolean] :apply_immediately

Indicates that the shard reconfiguration process begins immediately.
At present, the only permitted value for this parameter is `true`.

Value: true

@option params [Array<Types::ReshardingConfiguration>] :resharding_configuration

Specifies the preferred availability zones for each node group in the
cluster. If the value of `NodeGroupCount` is greater than the current
number of node groups (shards), you can use this parameter to specify
the preferred availability zones of the cluster's shards. If you omit
this parameter ElastiCache selects availability zones for you.

You can specify this parameter only if the value of `NodeGroupCount`
is greater than the current number of node groups (shards).

@option params [Array<String>] :node_groups_to_remove

If the value of `NodeGroupCount` is less than the current number of
node groups (shards), then either `NodeGroupsToRemove` or
`NodeGroupsToRetain` is required. `NodeGroupsToRemove` is a list of
`NodeGroupId`s to remove from the cluster.

ElastiCache for Redis will attempt to remove all node groups listed by
`NodeGroupsToRemove` from the cluster.

@option params [Array<String>] :node_groups_to_retain

If the value of `NodeGroupCount` is less than the current number of
node groups (shards), then either `NodeGroupsToRemove` or
`NodeGroupsToRetain` is required. `NodeGroupsToRetain` is a list of
`NodeGroupId`s to retain in the cluster.

ElastiCache for Redis will attempt to remove all node groups except
those listed by `NodeGroupsToRetain` from the cluster.

reboot_cache_cluster(params = {}, options = {}) click to toggle source

Reboots some, or all, of the cache nodes within a provisioned cluster. This operation applies any modified cache parameter groups to the cluster. The reboot operation takes place as soon as possible, and results in a momentary outage to the cluster. During the reboot, the cluster status is set to REBOOTING.

The reboot causes the contents of the cache (for each cache node being rebooted) to be lost.

When the reboot is complete, a cluster event is created.

Rebooting a cluster is currently supported on Memcached and Redis (cluster mode disabled) clusters. Rebooting is not supported on Redis (cluster mode enabled) clusters.

If you make changes to parameters that require a Redis (cluster mode enabled) cluster reboot for the changes to be applied, see [Rebooting a Cluster] for an alternate process.

[1]: docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Clusters.Rebooting.html

@option params [required, String] :cache_cluster_id

The cluster identifier. This parameter is stored as a lowercase
string.

@option params [required, Array<String>] :cache_node_ids_to_reboot

A list of cache node IDs to reboot. A node ID is a numeric identifier
(0001, 0002, etc.). To reboot an entire cluster, specify all of the
cache node IDs.

@return [Types::RebootCacheClusterResult] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

remove_tags_from_resource(params = {}, options = {}) click to toggle source

Removes the tags identified by the `TagKeys` list from the named resource. A tag is a key-value pair where the key and value are case-sensitive. You can use tags to categorize and track all your ElastiCache resources, with the exception of global replication group. When you add or remove tags on replication groups, those actions will be replicated to all nodes in the replication group. For more information, see [Resource-level permissions].

[1]: docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/IAM.ResourceLevelPermissions.html

@option params [required, String] :resource_name

The Amazon Resource Name (ARN) of the resource from which you want the
tags removed, for example

test_failover(params = {}, options = {}) click to toggle source

Represents the input of a `TestFailover` operation which test automatic failover on a specified node group (called shard in the console) in a replication group (called cluster in the console).

**Note the following**

  • A customer can use this operation to test automatic failover on up to 5 shards (called node groups in the ElastiCache API and Amazon CLI) in any rolling 24-hour period.

  • If calling this operation on shards in different clusters (called replication groups in the API and CLI), the calls can be made concurrently.

  • If calling this operation multiple times on different shards in the same Redis (cluster mode enabled) replication group, the first node replacement must complete before a subsequent call can be made.

  • To determine whether the node replacement is complete you can check Events using the Amazon ElastiCache console, the Amazon CLI, or the ElastiCache API. Look for the following automatic failover related events, listed here in order of occurrance:

    1. Replication group message: `Test Failover API called for node group <node-group-id>`

    2. Cache cluster message: `Failover from primary node <primary-node-id> to replica node <node-id> completed`

    3. Replication group message: `Failover from primary node <primary-node-id> to replica node <node-id> completed`

    4. Cache cluster message: `Recovering cache nodes <node-id>`

    5. Cache cluster message: `Finished recovery for cache nodes <node-id>`

wait_until(waiter_name, params = {}, options = {}) { |waiter| ... } click to toggle source

Polls an API operation until a resource enters a desired state.

## Basic Usage

A waiter will call an API operation until:

  • It is successful

  • It enters a terminal state

  • It makes the maximum number of attempts

In between attempts, the waiter will sleep.

# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.

# poll for ~25 seconds
client.wait_until(waiter_name, params, {
  max_attempts: 5,
  delay: 5,
})

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw `:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(waiter_name, params, {

  # disable max attempts
  max_attempts: nil,

  # poll for 1 hour, instead of a number of attempts
  before_wait: -> (attempts, response) do
    throw :failure if Time.now - started_at > 3600
  end
})

## Handling Errors

When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from {Aws::Waiters::Errors::WaiterFailed}.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

## Valid Waiters

The following table lists the valid waiter names, the operations they call, and the default `:delay` and `:max_attempts` values.

| waiter_name | params | :delay | :max_attempts | | ————————— | ———————————— | ——– | ————- | | cache_cluster_available | {Client#describe_cache_clusters} | 15 | 40 | | cache_cluster_deleted | {Client#describe_cache_clusters} | 15 | 40 | | replication_group_available | {Client#describe_replication_groups} | 15 | 40 | | replication_group_deleted | {Client#describe_replication_groups} | 15 | 40 |

@raise [Errors::FailureStateError] Raised when the waiter terminates

because the waiter has entered a state that it will not transition
out of, preventing success.

@raise [Errors::TooManyAttemptsError] Raised when the configured

maximum number of attempts have been made, and the waiter is not
yet successful.

@raise [Errors::UnexpectedError] Raised when an error is encounted

while polling for a resource that is not expected.

@raise [Errors::NoSuchWaiterError] Raised when you request to wait

for an unknown state.

@return [Boolean] Returns `true` if the waiter was successful. @param [Symbol] waiter_name @param [Hash] params ({}) @param [Hash] options ({}) @option options [Integer] :max_attempts @option options [Integer] :delay @option options [Proc] :before_attempt @option options [Proc] :before_wait
