Instance Attribute Details

#at_rest_encryption_enabled ⇒ `Boolean`

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)

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:

#cache_node_type ⇒ `String`

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:
  
  M7g node types: cache.m7g.large, cache.m7g.xlarge, cache.m7g.2xlarge, cache.m7g.4xlarge, cache.m7g.8xlarge, cache.m7g.12xlarge, cache.m7g.16xlarge

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.

#cache_parameter_group_name ⇒ `String`

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 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)

#cache_subnet_group_name ⇒ `String`

The name of the cache subnet group to be used for the replication group.

If you're going to launch your cluster in an Amazon VPC, you need to create a subnet group before you start creating a cluster. For more information, see Subnets and Subnet Groups.

#cluster_mode ⇒ `String`

Enabled or Disabled. To modify cluster mode from Disabled to Enabled, you must first set the cluster mode to Compatible. Compatible mode allows your Redis clients to connect using both cluster mode enabled and cluster mode disabled. After you migrate all Redis clients to use cluster mode enabled, you can then complete cluster mode configuration and set the cluster mode to Enabled.

#engine_version ⇒ `String`

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_configuration ⇒ `Array<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:

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.

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.

#transit_encryption_enabled ⇒ `Boolean`

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

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)

end

#transit_encryption_mode ⇒ `String`

A setting that allows you to migrate your clients to use in-transit encryption, with no downtime.

When setting TransitEncryptionEnabled to true, you can set your TransitEncryptionMode to preferred in the same request, to allow both encrypted and unencrypted connections at the same time. Once you migrate all your Redis clients to use encrypted connections you can modify the value to required to allow encrypted connections only.

Setting TransitEncryptionMode to required is a two-step process that requires you to first set the TransitEncryptionMode to preferred, after that you can set TransitEncryptionMode to required.

This process will not trigger the replacement of the replication group.

Returns:

(String)
