| cache_node_type | core | string | The cache node type for the reserved cache nodes. 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 For region availability, see Supported Node Types 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 For region availability, see Supported Node Types 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. |
