Method: Aws::ElastiCache::Types::CreateReplicationGroupMessage#cache_node_type

Defined in:
lib/aws-sdk-elasticache/types.rb

#cache_node_type ⇒ String

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:

      **M7g node types**: cache.m7g.large, cache.m7g.xlarge, cache.m7g.2xlarge, cache.m7g.4xlarge, cache.m7g.8xlarge, cache.m7g.12xlarge, cache.m7g.16xlarge

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

      </note>

      **M6g node types** (available only for Redis OSS 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

      **M5 node types:** cache.m5.large, cache.m5.xlarge, cache.m5.2xlarge, cache.m5.4xlarge, cache.m5.12xlarge, cache.m5.24xlarge

      **M4 node types:** cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlarge

      **T4g node types** (available only for Redis OSS engine version 5.0.6 onward and Memcached engine version 1.5.16 onward): cache.t4g.micro, cache.t4g.small, cache.t4g.medium

      **T3 node types:** cache.t3.micro, cache.t3.small, cache.t3.medium

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

    • Previous generation: (not recommended. Existing clusters are still supported but creation of new clusters is not supported for these types.)

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

      **M1 node types:** cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge

      **M3 node types:** cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge

  • Compute optimized:

    • Previous generation: (not recommended. Existing clusters are still supported but creation of new clusters is not supported for these types.)

      **C1 node types:** cache.c1.xlarge

  • Memory optimized:

    • Current generation:

      **R7g node types**: cache.r7g.large, cache.r7g.xlarge, cache.r7g.2xlarge, cache.r7g.4xlarge, cache.r7g.8xlarge, cache.r7g.12xlarge, cache.r7g.16xlarge

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

      </note>

      **R6g node types** (available only for Redis OSS 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, cache.r6g.16xlarge

      **R5 node types:** cache.r5.large, cache.r5.xlarge, cache.r5.2xlarge, cache.r5.4xlarge, cache.r5.12xlarge, cache.r5.24xlarge

      **R4 node types:** cache.r4.large, cache.r4.xlarge, cache.r4.2xlarge, cache.r4.4xlarge, cache.r4.8xlarge, cache.r4.16xlarge

    • Previous generation: (not recommended. Existing clusters are still supported but creation of new clusters is not supported for these types.)

      **M2 node types:** cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge

      **R3 node types:** cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge

**Additional node type info**

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

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

  • Valkey or Redis OSS Multi-AZ with automatic failover is not supported on T1 instances.

  • The configuration variables appendonly and appendfsync are not supported on Valkey, or on Redis OSS version 2.8.22 and later.
