ReplicationGroup

Contains all of the attributes of a specific Redis replication group.

Contents

Note

In the following list, the required parameters are described first.

AtRestEncryptionEnabled

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

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

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

Default: false

Type: Boolean

Required: No

AuthTokenEnabled

A flag that enables using an AuthToken (password) when issuing Redis commands.

Default: false

Type: Boolean

Required: No

AutomaticFailover

Indicates the status of Multi-AZ with automatic failover for this Redis replication group.

Amazon ElastiCache for Redis does not support Multi-AZ with automatic failover on:

  • Redis versions earlier than 2.8.6.

  • Redis (cluster mode disabled): T1 node types.

  • Redis (cluster mode enabled): T1 node types.

Type: String

Valid Values: enabled | disabled | enabling | disabling

Required: No

CacheNodeType

The name of the compute and memory capacity node type for each node in the replication group.

Type: String

Required: No

ClusterEnabled

A flag indicating whether or not this replication group is cluster enabled; i.e., whether its data can be partitioned across multiple shards (API/CLI: node groups).

Valid values: true | false

Type: Boolean

Required: No

ConfigurationEndpoint

The configuration endpoint for this replication group. Use the configuration endpoint to connect to this replication group.

Type: Endpoint object

Required: No

Description

The user supplied description of the replication group.

Type: String

Required: No

KmsKeyId

The ID of the KMS key used to encrypt the disk in the cluster.

Type: String

Required: No

MemberClusters.ClusterId.N

The names of all the cache clusters that are part of this replication group.

Type: Array of strings

Required: No

NodeGroups.NodeGroup.N

A list of node groups in this replication group. For Redis (cluster mode disabled) replication groups, this is a single-element list. For Redis (cluster mode enabled) replication groups, the list contains an entry for each node group (shard).

Type: Array of NodeGroup objects

Required: No

PendingModifiedValues

A group of settings to be applied to the replication group, either immediately or during the next maintenance window.

Type: ReplicationGroupPendingModifiedValues object

Required: No

ReplicationGroupId

The identifier for the replication group.

Type: String

Required: No

SnapshotRetentionLimit

The number of days for which ElastiCache retains automatic cluster snapshots before deleting them. For example, if you set SnapshotRetentionLimit to 5, a snapshot that was taken today is retained for 5 days before being deleted.

Important

If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off.

Type: Integer

Required: No

SnapshottingClusterId

The cluster ID that is used as the daily snapshot source for the replication group.

Type: String

Required: No

SnapshotWindow

The daily time range (in UTC) during which ElastiCache begins taking a daily snapshot of your node group (shard).

Example: 05:00-09:00

If you do not specify this parameter, ElastiCache automatically chooses an appropriate time range.

Note

This parameter is only valid if the Engine parameter is redis.

Type: String

Required: No

Status

The current state of this replication group - creating, available, modifying, deleting, create-failed, snapshotting.

Type: String

Required: No

TransitEncryptionEnabled

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.

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

Default: false

Type: Boolean

Required: No
