Represents an individual cache node within a cluster. Each cache node runs its own instance of the cluster's protocol-compliant caching software - either Memcached or Redis.

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

    For region availability, see Supported Node Types

    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 engine version 5.0.6 onward and for 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)

    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)

    C1 node types: cache.c1.xlarge

• Memory optimized with data tiering:

  • Current generation:

    R6gd node types (available only for Redis engine version 6.2 onward).

    cache.r6gd.xlarge, cache.r6gd.2xlarge, cache.r6gd.4xlarge, cache.r6gd.8xlarge, cache.r6gd.12xlarge, cache.r6gd.16xlarge

• 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, 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)

    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.

• 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.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cache_node_id: Option<String>

The cache node identifier. A node ID is a numeric identifier (0001, 0002, etc.). The combination of cluster ID and node ID uniquely identifies every cache node used in a customer's Amazon account.

cache_node_status: Option<String>

The current state of this cache node, one of the following values: available, creating, rebooting, or deleting.

cache_node_create_time: Option<DateTime>

The date and time when the cache node was created.

endpoint: Option<Endpoint>

The hostname for connecting to this cache node.

parameter_group_status: Option<String>

The status of the parameter group applied to this cache node.

source_cache_node_id: Option<String>

The ID of the primary node to which this read replica node is synchronized. If this field is empty, this node is not associated with a primary cluster.

customer_availability_zone: Option<String>

The Availability Zone where this node was created and now resides.

customer_outpost_arn: Option<String>

The customer outpost ARN of the cache node.
