class Aws::TimestreamQuery::Client
An API client for TimestreamQuery
. To construct a client, you need to configure a `:region` and `:credentials`.
client = Aws::TimestreamQuery::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: * `Aws.config[:region]` * `ENV['AWS_REGION']` * `ENV['AMAZON_REGION']` * `ENV['AWS_DEFAULT_REGION']` * `~/.aws/credentials` * `~/.aws/config` @option options [String] :access_key_id @option options [Boolean] :active_endpoint_cache (false) When set to `true`, a thread polling for endpoints will be running in the background every 60 secs (default). Defaults to `false`. @option options [Boolean] :adaptive_retry_wait_to_fill (true) Used only in `adaptive` retry mode. When true, the request will sleep until there is sufficent client side capacity to retry the request. When false, the request will raise a `RetryCapacityNotAvailableError` and will not retry instead of sleeping. @option options [Boolean] :client_side_monitoring (false) When `true`, client-side metrics will be collected for all API requests from this client. @option options [String] :client_side_monitoring_client_id ("") Allows you to provide an identifier for this client which will be attached to all generated client side metrics. Defaults to an empty string. @option options [String] :client_side_monitoring_host ("127.0.0.1") Allows you to specify the DNS hostname or IPv4 or IPv6 address that the client side monitoring agent is running on, where client metrics will be published via UDP. @option options [Integer] :client_side_monitoring_port (31000) Required for publishing client metrics. The port that the client side monitoring agent is running on, where client metrics will be published via UDP. @option options [Aws::ClientSideMonitoring::Publisher] :client_side_monitoring_publisher (Aws::ClientSideMonitoring::Publisher) Allows you to provide a custom client-side monitoring publisher class. By default, will use the Client Side Monitoring Agent Publisher. @option options [Boolean] :convert_params (true) 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. @option options [Integer] :endpoint_cache_max_threads (10) Used for the maximum threads in use for polling endpoints to be cached, defaults to 10. @option options [Integer] :endpoint_cache_poll_interval (60) When :endpoint_discovery and :active_endpoint_cache is enabled, Use this option to config the time interval in seconds for making requests fetching endpoints information. Defaults to 60 sec. @option options [Boolean] :endpoint_discovery (true) When set to `true`, endpoint discovery will be enabled for operations when available. @option options [Aws::Log::Formatter] :log_formatter (Aws::Log::Formatter.default) The log formatter. @option options [Symbol] :log_level (:info) The log level to send messages to the `:logger` at. @option options [Logger] :logger The Logger instance to send log messages to. If this option 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] :simple_json (false) Disables request parameter conversion, validation, and formatting. Also disable response data type conversions. This option is useful when you want to ensure the highest level of performance by avoiding overhead of walking request parameters and response data structures. When `:simple_json` is enabled, the request parameters hash must be formatted exactly as the DynamoDB API expects. @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.

Cancels a query that has been issued. Cancellation is guaranteed only if the query has not completed execution before the cancellation request was issued. Because cancellation is an idempotent operation, subsequent cancellation requests will return a `CancellationMessage`, indicating that the query has already been canceled.
@option params [required, String] :query_id
The id of the query that needs to be cancelled. `QueryID` is returned as part of QueryResult.
@return [Types::CancelQueryResponse] Returns a {Seahorse::Client::Response response} object which responds to the following methods:
* {Types::CancelQueryResponse#cancellation_message #cancellation_message} => String
@example Request syntax with placeholder values
resp = client.cancel_query({ query_id: "QueryId", # required })

DescribeEndpoints returns a list of available endpoints to make Timestream API calls against. This API is available through both Write and Query.
Because Timestream’s SDKs are designed to transparently work with the service’s architecture, including the management and mapping of the service endpoints, *it is not recommended that you use this API unless*:
-
Your application uses a programming language that does not yet have SDK support
-
You require better control over the client-side implementation
For detailed information on how to use DescribeEndpoints, see [The Endpoint Discovery Pattern and REST APIs].

Query is a synchronous operation that enables you to execute a query. Query will timeout after 60 seconds. You must update the default timeout in the SDK to support a timeout of 60 seconds. The result set will be truncated to 1MB. Service quotas apply. For more information, see Quotas in the Timestream Developer Guide.
@option params [required, String] :query_string
The query to be executed by Timestream.
@option params [String] :client_token
Unique, case-sensitive string of up to 64 ASCII characters that you specify when you make a Query request. Providing a `ClientToken` makes the call to `Query` idempotent, meaning that multiple identical calls have the same effect as one single call. Your query request will fail in the following cases: * If you submit a request with the same client token outside the 5-minute idepotency window. * If you submit a request with the same client token but a change in other parameters within the 5-minute idempotency window. After 4 hours, any request with the same client token is treated as a new request. **A suitable default value is auto-generated.** You should normally not need to pass this option.**
@option params [String] :next_token
A pagination token passed to get a set of results.
@option params [Integer] :max_rows
The total number of rows to return in the output. If the total number of rows available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command.
@return [Types::QueryResponse] Returns a {Seahorse::Client::Response response} object which responds to the following methods:
* {Types::QueryResponse#query_id #query_id} => String * {Types::QueryResponse#next_token #next_token} => String * {Types::QueryResponse#rows #rows} => Array<Types::Row> * {Types::QueryResponse#column_info #column_info} => Array<Types::ColumnInfo> * {Types::QueryResponse#query_status #query_status} => Types::QueryStatus
The returned {Seahorse::Client::Response response} is a pageable response and is Enumerable. For details on usage see {Aws::PageableResponse PageableResponse}.
