Overview

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

      At this time, M6g node types are available in the following regions: us-east-1, us-west-2, us-east-2, eu-central-1, eu-west-1 and ap-northeast-1.

      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

      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:

    • 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

      At this time, R6g node types are available in the following regions: us-east-1, us-west-2, us-east-2, eu-central-1, eu-west-1 and ap-northeast-1.

      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.

Instance Attribute Details

#cache_node_create_timeTime

The date and time when the cache node was created.

Returns:

  • (Time)

    The date and time when the cache node was created.

#cache_node_idString

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 AWS account.

Returns:

  • (String)

    The cache node identifier.

#cache_node_statusString

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

Returns:

  • (String)

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

#customer_availability_zoneString

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

Returns:

  • (String)

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

#customer_outpost_arnString

The customer outpost ARN of the cache node.

Returns:

  • (String)

    The customer outpost ARN of the cache node.

#endpointTypes::Endpoint

The hostname for connecting to this cache node.

Returns:

#parameter_group_statusString

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

Returns:

  • (String)

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

#source_cache_node_idString

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.

Returns:

  • (String)

    The ID of the primary node to which this read replica node is synchronized.
