cacheNodeType

The cache node type for the reserved cache node.

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.16xlargeFor region availability, see Supported Node TypesM6g 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.16xlargeM5 node types:cache.m5.large, cache.m5.xlarge, cache.m5.2xlarge, cache.m5.4xlarge, cache.m5.12xlarge, cache.m5.24xlargeM4 node types:cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlargeT4g 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.mediumT3 node types:cache.t3.micro, cache.t3.small, cache.t3.mediumT2 node types:cache.t2.micro, cache.t2.small, cache.t2.medium

Existing clusters are still supported but creation of new clusters is not supported for these types.)T1 node types:cache.t1.microM1 node types:cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlargeM3 node types:cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge

• Compute optimized:

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.
