Specifies whether the nodes in this Memcached node group 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 cache clusters.

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

This parameter is currently disabled.

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

Constraints:

A name must contain from 1 to 20 alphanumeric characters or hyphens. The first character must be a letter. A name cannot end with a hyphen or contain two consecutive hyphens.

The compute and memory capacity of the nodes in the node group.

Valid node types are as follows:

General purpose: Current generation: 'cache.t2.micro', 'cache.t2.small', 'cache.t2.medium', 'cache.m3.medium', 'cache.m3.large', 'cache.m3.xlarge', 'cache.m3.2xlarge' Previous generation: 'cache.t1.micro', 'cache.m1.small', 'cache.m1.medium', 'cache.m1.large', 'cache.m1.xlarge' Compute optimized: 'cache.c1.xlarge' Memory optimized Current generation: 'cache.r3.large', 'cache.r3.xlarge', 'cache.r3.2xlarge', 'cache.r3.4xlarge', 'cache.r3.8xlarge' Previous generation: 'cache.m2.xlarge', 'cache.m2.2xlarge', 'cache.m2.4xlarge' Notes:

All t2 instances are created in an Amazon Virtual Private Cloud (VPC). Redis backup/restore is not supported for t2 instances. Redis Append-only files (AOF) functionality is not supported for t1 or t2 instances. For a complete listing of cache node types and specifications, see Amazon ElastiCache Product Features and Details and Cache NodeType-Specific Parameters for Memcached or Cache Node Type-Specific Parametersfor Redis.

The name of the parameter group to associate with this cache cluster. If this argument is omitted, the default parameter group for the specified engine is used.

A list of security group names to associate with this cache cluster.

Use this parameter only when you are creating a cache cluster outside of an Amazon Virtual Private Cloud (VPC).

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

Use this parameter only when you are creating a cache cluster in an Amazon Virtual Private Cloud (VPC).

The name of the cache engine to be used for this cache cluster.

Valid values for this parameter are:

memcached | redis

The version number of the cache engine to be used for this cache cluster. To view the supported cache engine versions, use the DescribeCacheEngineVersions action.

The Amazon Resource Name (ARN) of the Amazon Simple Notification Service (SNS) topic to which notifications will be sent.

The Amazon SNS topic owner must be the same as the cache cluster owner.

The initial number of cache nodes that the cache cluster will have.

For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 20.

If you need more than 20 nodes for your Memcached cluster, please fill out the ElastiCache Limit Increase Request form at http://aws.amazon.com/contact-us/elasticache-node-limit-request/.

The port number on which each of the cache nodes will accept connections.

The EC2 Availability Zone in which the cache cluster will be created.

All nodes belonging to this Memcached cache 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.

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

This option is only supported on Memcached.

If you are creating your cache 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.

Example: One Memcached node in each of three different Availability Zones: 'PreferredAvailabilityZones.member.1=us-west-2a&PreferredAvailabilityZones.member.2=us-west-2b&PreferredAvailabilityZones.member.3=us-west-2c'

Example: All three Memcached nodes in one Availability Zone: 'PreferredAvailabilityZones.member.1=us-west-2a&PreferredAvailabilityZones.member.2=us-west-2a&PreferredAvailabilityZones.member.3=us-west-2a'

Specifies the weekly time range during which maintenance on the cache cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period. Valid values for ddd are:

sun mon tue wed thu fri sat Example: 'sun:05:00-sun:09:00'

The ID of the replication group to which this cache cluster should belong. If this parameter is specified, the cache cluster will be added to the specified replication group as a read replica; otherwise, the cache cluster will be 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 cache cluster will be 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.

One or more VPC security groups associated with the cache cluster.

Use this parameter only when you are creating a cache cluster in an Amazon Virtual Private Cloud (VPC).

A single-element string list containing an Amazon Resource Name (ARN) that uniquely identifies a Redis RDB snapshot file stored in Amazon S3. The snapshot file will be used to populate the node group. The Amazon S3 object name in the ARN cannot contain any commas.

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

Example of an Amazon S3 ARN: 'arn:aws:s3:::my_bucket/snapshot1.rdb'

The name of a snapshot from which to restore data into the new node group. The snapshot status changes to restoring while the new node group is being created.

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

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

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

Default: 0 (i.e., automatic backups are disabled for this cache cluster).

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

Example: '05:00-09:00'

If you do not specify this parameter, then ElastiCache will automatically choose an appropriate time range.

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

A list of cost allocation tags to be added to this resource. A tag is a key-value pair. A tag key must be accompanied by a tag value.
