{'ServerlessCacheSnapshotName': 'string'}

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

This API can be used to create a standalone regional replication group or a secondary replication group associated with a Global datastore.

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 cluster is comprised of from 1 to 90 shards (API/CLI: node groups). Each shard has a primary node and up to 5 read-only replica nodes. The configuration can range from 90 shards and 0 replicas to 15 shards and 5 replicas, which is the maximum number or replicas allowed.

The node or shard limit can be increased to a maximum of 500 per cluster if the Redis engine version is 5.0.6 or higher. For example, you can choose to configure a 500 node cluster that ranges between 83 shards (one primary and 5 replicas per shard) and 500 shards (single primary and no replicas). Make sure there are enough available IP addresses to accommodate the increase. Common pitfalls include the subnets in the subnet group have too small a CIDR range or the subnets are shared and heavily used by other clusters. For more information, see Creating a Subnet Group . For versions below 5.0.6, the limit is 250 per cluster.

To request a limit increase, see Amazon Service Limits and choose the limit type Nodes per cluster per instance type .

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. If you need to increase or decrease the number of node groups (console: shards), you can avail yourself of ElastiCache for Redis' scaling. For more information, see Scaling ElastiCache for Redis Clusters in the ElastiCache User Guide .

Note

This operation is valid for Redis only.

  • A name cannot end with a hyphen or contain two consecutive hyphens.

type ReplicationGroupDescription

string

param ReplicationGroupDescription

[REQUIRED]

A user-created description for the replication group.

type GlobalReplicationGroupId

string

param GlobalReplicationGroupId

The name of the Global datastore

type PrimaryClusterId

string

param PrimaryClusterId

The identifier of the cluster that serves as the primary for this replication group. This cluster must already exist and have a status of available .

This parameter is not required if NumCacheClusters , NumNodeGroups , or ReplicasPerNodeGroup is specified.

type AutomaticFailoverEnabled

boolean

param AutomaticFailoverEnabled

AutomaticFailoverEnabled must be enabled for Redis (cluster mode enabled) replication groups.

Default: false

type MultiAZEnabled

boolean

param MultiAZEnabled

A flag indicating if you have Multi-AZ enabled to enhance fault tolerance. For more information, see Minimizing Downtime: Multi-AZ .

type NumCacheClusters

integer

param NumCacheClusters

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).

type PreferredCacheClusterAZs

list

param PreferredCacheClusterAZs

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.

Note

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.

  • (string) --

type NumNodeGroups

integer

param NumNodeGroups

An optional parameter that specifies the number of node groups (shards) for this Redis (cluster mode enabled) replication group. For Redis (cluster mode disabled) either omit this parameter or set it to 1.

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.

type TransitEncryptionMode

string

param TransitEncryptionMode

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.

type ClusterMode

string

param ClusterMode

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.

type ServerlessCacheSnapshotName

string

param ServerlessCacheSnapshotName

Returns events related to clusters, cache security groups, and cache parameter groups. You can obtain events specific to a particular cluster, cache security group, or cache parameter group by providing the name as a parameter.

By default, only the events occurring within the last hour are returned; however, you can retrieve up to 14 days' worth of events if necessary.
