class Aws::ElastiCache::Types::DescribeReservedCacheNodesOfferingsMessage

Represents the input of a `DescribeReservedCacheNodesOfferings` operation.

@note When making an API call, you may pass DescribeReservedCacheNodesOfferingsMessage

data as a hash:

    {
      reserved_cache_nodes_offering_id: "String",
      cache_node_type: "String",
      duration: "String",
      product_description: "String",
      offering_type: "String",
      max_records: 1,
      marker: "String",
    }

@!attribute [rw] reserved_cache_nodes_offering_id

The offering identifier filter value. Use this parameter to show
only the available offering that matches the specified reservation
identifier.

Example: `438012d3-4052-4cc7-b2e3-8d3372e0e706`
@return [String]

@!attribute [rw] cache_node_type

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

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`

    `cache.t3.medium`

    **T2 node types:** `cache.t2.micro`, `cache.t2.small`,
    `cache.t2.medium`

  * Previous generation: (not recommended)

    **T1 node types:** `cache.t1.micro`

    **M1 node types:** `cache.m1.small`, `cache.m1.medium`,

* Memory optimized:

  * Current generation:

    **R6g node types** (available only for Redis engine version
    5.0.6 onward and for Memcached engine version 1.5.16 onward).

    `cache.r6g.large`, `cache.r6g.xlarge`, `cache.r6g.2xlarge`,
    `cache.r6g.4xlarge`, `cache.r6g.8xlarge`, `cache.r6g.12xlarge`,

**Additional node type info**

* All current generation instance types are created in Amazon VPC by
  default.

* Redis append-only files (AOF) are not supported for T1 or T2
  instances.

* Redis Multi-AZ with automatic failover is not supported on T1
  instances.

* Redis configuration variables `appendonly` and `appendfsync` are
  not supported on Redis version 2.8.22 and later.
