Amazon ElastiCache

2022/05/23 - Amazon ElastiCache - 1 updated api methods

Changes  Added support for encryption in transit for Memcached clusters. Customers can now launch Memcached cluster with encryption in transit enabled when using Memcached version 1.6.12 or later.

CreateCacheCluster (updated) Link ΒΆ
Changes (request)
{'TransitEncryptionEnabled': 'boolean'}

Creates a cluster. All nodes in the cluster run the same protocol-compliant cache engine software, either Memcached or Redis.

This operation is not supported for Redis (cluster mode enabled) clusters.

type CacheClusterId

string

param CacheClusterId

[REQUIRED]

The node group (shard) identifier. This parameter is stored as a lowercase string.

Constraints:

  • A name must contain from 1 to 50 alphanumeric characters or hyphens.

  • The first character must be a letter.

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

type ReplicationGroupId

string

param ReplicationGroupId

The ID of the replication group to which this cluster should belong. If this parameter is specified, the cluster is added to the specified replication group as a read replica; otherwise, the cluster is a standalone primary that is not part of any replication group.

If the specified replication group is Multi-AZ enabled and the Availability Zone is not specified, the cluster is created in Availability Zones that provide the best spread of read replicas across Availability Zones.

Note

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

type AZMode

string

param AZMode

Specifies whether the nodes in this Memcached cluster are created in a single Availability Zone or created across multiple Availability Zones in the cluster's region.

This parameter is only supported for Memcached clusters.

If the AZMode and PreferredAvailabilityZones are not specified, ElastiCache assumes single-az mode.

type PreferredAvailabilityZone

string

param PreferredAvailabilityZone

The EC2 Availability Zone in which the cluster is created.

All nodes belonging to this cluster are placed in the preferred Availability Zone. If you want to create your nodes across multiple Availability Zones, use PreferredAvailabilityZones .

Default: System chosen Availability Zone.

type PreferredAvailabilityZones

list

param PreferredAvailabilityZones

A list of the Availability Zones in which cache nodes are created. The order of the zones in the list is not important.

This option is only supported on Memcached.

Note

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

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

If you want all the nodes in the same Availability Zone, use PreferredAvailabilityZone instead, or repeat the Availability Zone multiple times in the list.

Default: System chosen Availability Zones.

  • (string) --

type NumCacheNodes

integer

param NumCacheNodes

The initial number of cache nodes that the cluster has.

For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 40.
