Instance Attribute Details

#at_rest_encryption_enabledBoolean

A flag that enables encryption at rest when set to true.

You cannot modify the value of AtRestEncryptionEnabled after the replication group is created. To enable encryption at rest on a replication group you must set AtRestEncryptionEnabled to true when you create the replication group.

Required: Only available when creating a replication group in an Amazon VPC using redis version 3.2.6, 4.x or later.

Default: false

Returns:

  • (Boolean)

#auth_tokenString

Reserved parameter. The password used to access a password protected server.

AuthToken can be specified only on replication groups where TransitEncryptionEnabled is true.

For HIPAA compliance, you must specify TransitEncryptionEnabled as true, an AuthToken, and a CacheSubnetGroup.

Password constraints:

  • Must be only printable ASCII characters.

  • Must be at least 16 characters and no more than 128 characters in length.

  • The only permitted printable special characters are !, &, #, $, ^, <, >, and -. Other printable special characters cannot be used in the AUTH token.

For more information, see AUTH password at http://redis.io/commands/AUTH.

Returns:

  • (String)

#cache_node_typeString

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:

      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:

      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.

Returns:

  • (String)

#cache_parameter_group_nameString

The name of the parameter group to associate with this replication group. If this argument is omitted, the default cache parameter group for the specified engine is used.

If you are restoring to an engine version that is different than the original, you must specify the default version of that version. For example, CacheParameterGroupName=default.redis4.0.

If you are running Redis version 3.2.4 or later, only one node group (shard), and want to use a default parameter group, we recommend that you specify the parameter group by name.

  • To create a Redis (cluster mode disabled) replication group, use CacheParameterGroupName=default.redis3.2.

  • To create a Redis (cluster mode enabled) replication group, use CacheParameterGroupName=default.redis3.2.cluster.on.

Returns:

  • (String)

#engine_versionString

The version number of the cache engine to be used for the clusters in this replication group. To view the supported cache engine versions, use the DescribeCacheEngineVersions operation.

Important: You can upgrade to a newer engine version (see Selecting a Cache Engine and Version) in the ElastiCache User Guide, but you cannot downgrade to an earlier engine version. If you want to use an earlier engine version, you must delete the existing cluster or replication group and create it anew with the earlier engine version.

Returns:

#node_group_configurationArray<Types::NodeGroupConfiguration>

A list of node group (shard) configuration options. Each node group (shard) configuration has the following members: PrimaryAvailabilityZone, ReplicaAvailabilityZones, ReplicaCount, and Slots.

If you're creating a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group, you can use this parameter to individually configure each node group (shard), or you can omit this parameter. However, it is required when seeding a Redis (cluster mode enabled) cluster from a S3 rdb file. You must configure each node group (shard) using this parameter because you must specify the slots for each node group.

Returns:

#num_cache_clustersInteger

The number of clusters this replication group initially has.

This parameter is not used if there is more than one node group (shard). You should use ReplicasPerNodeGroup instead.

If AutomaticFailoverEnabled is true, the value of this parameter must be at least 2. If AutomaticFailoverEnabled is false you can omit this parameter (it will default to 1), or you can explicitly set it to a value between 2 and 6.

The maximum permitted value for NumCacheClusters is 6 (1 primary plus 5 replicas).

#preferred_cache_cluster_a_zsArray<String>

A list of EC2 Availability Zones in which the replication group's clusters are created. The order of the Availability Zones in the list is the order in which clusters are allocated. The primary cluster is created in the first AZ in the list.

This parameter is not used if there is more than one node group (shard). You should use NodeGroupConfiguration instead.

If you are creating your replication group in an Amazon VPC (recommended), you can only locate clusters in Availability Zones associated with the subnets in the selected subnet group.

The number of Availability Zones listed must equal the value of NumCacheClusters.

Default: system chosen Availability Zones.

Returns:

#transit_encryption_enabledBoolean

A flag that enables in-transit encryption when set to true.

You cannot modify the value of TransitEncryptionEnabled after the cluster is created. To enable in-transit encryption on a cluster you must set TransitEncryptionEnabled to true when you create a cluster.

This parameter is valid only if the Engine parameter is redis, the EngineVersion parameter is 3.2.6, 4.x or later, and the cluster is being created in an Amazon VPC.

If you enable in-transit encryption, you must also specify a value for CacheSubnetGroup.

Required: Only available when creating a replication group in an Amazon VPC using redis version 3.2.6, 4.x or later.

Default: false

For HIPAA compliance, you must specify TransitEncryptionEnabled as true, an AuthToken, and a CacheSubnetGroup.

Returns:

  • (Boolean)
