Network.AWS.ElastiCache.CreateReplicationGroup

Creates a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group.

A Redis (cluster mode disabled) replication group is a collection of clusters, where one of the clusters is a read/write primary and the others are read-only replicas. Writes to the primary are asynchronously propagated to the replicas.

A Redis (cluster mode enabled) replication group is a collection of 1 to 15 node groups (shards). Each node group (shard) has one read/write primary node and up to 5 read-only replica nodes. Writes to the primary are asynchronously propagated to the replicas. Redis (cluster mode enabled) replication groups partition the data across node groups (shards).

When a Redis (cluster mode disabled) replication group has been successfully created, you can add one or more read replicas to it, up to a total of 5 read replicas. You cannot alter a Redis (cluster mode enabled) replication group after it has been created. However, if you need to increase or decrease the number of node groups (console: shards), you can avail yourself of ElastiCache for Redis' enhanced backup and restore. For more information, see Restoring From a Backup with Cluster Resizing in the ElastiCache User Guide .

crgReplicationGroupDescription

-> CreateReplicationGroup

Creates a value of CreateReplicationGroup with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• crgAutomaticFailoverEnabled - Specifies whether a read-only replica is automatically promoted to read/write primary if the existing primary fails. If true , Multi-AZ is enabled for this replication group. If false , Multi-AZ is disabled for this replication group. AutomaticFailoverEnabled must be enabled for Redis (cluster mode enabled) replication groups. Default: false 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 and T2 cache node types. * Redis (cluster mode enabled): T1 node types.
• crgEngineVersion - 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.
• crgCacheNodeType - 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: T2 node types: cache.t2.micro , cache.t2.small , cache.t2.medium M3 node types: cache.m3.medium , cache.m3.large , cache.m3.xlarge , cache.m3.2xlarge M4 node types: cache.m4.large , cache.m4.xlarge , cache.m4.2xlarge , cache.m4.4xlarge , cache.m4.10xlarge * 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 * Compute optimized: * Previous generation: (not recommended) C1 node types: cache.c1.xlarge * Memory optimized: * Current generation: R3 node types: cache.r3.large , cache.r3.xlarge , cache.r3.2xlarge , cache.r3.4xlarge , cache.r3.8xlarge * Previous generation: (not recommended) M2 node types: cache.m2.xlarge , cache.m2.2xlarge , cache.m2.4xlarge Notes: * All T2 instances are created in an Amazon Virtual Private Cloud (Amazon VPC). * Redis (cluster mode disabled): Redis backuprestore is not supported on T1 and T2 instances. * Redis (cluster mode enabled): Backuprestore is not supported on T1 instances. * Redis Append-only files (AOF) functionality is not supported for T1 or T2 instances. For a complete listing of node types and specifications, see Amazon ElastiCache Product Features and Details and either Cache Node Type-Specific Parameters for Memcached or Cache Node Type-Specific Parameters for Redis .

Example of an Amazon S3 ARN: arn:aws:s3:::my_bucket/snapshot1.rdb
• crgAutoMinorVersionUpgrade - This parameter is currently disabled.
• crgCacheParameterGroupName - 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 .
• crgTransitEncryptionEnabled - 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.
