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

preferred_availability_zone instance-attribute 

preferred_availability_zone: NotRequired[String]

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.

preferred_availability_zones instance-attribute 

preferred_availability_zones: NotRequired[PreferredAvailabilityZoneList]

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.

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.

preferred_maintenance_window instance-attribute 

preferred_maintenance_window: NotRequired[String]

Specifies the weekly time range during which maintenance on the 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.

preferred_outpost_arn instance-attribute 

preferred_outpost_arn: NotRequired[String]

The outpost ARN in which the cache cluster is created.

preferred_outpost_arns instance-attribute 

preferred_outpost_arns: NotRequired[PreferredOutpostArnList]

The outpost ARNs in which the cache cluster is created.

replication_group_id instance-attribute 

replication_group_id: NotRequired[String]

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.

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

security_group_ids instance-attribute 

security_group_ids: NotRequired[SecurityGroupIdsList]

One or more VPC security groups associated with the cluster.

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

snapshot_arns instance-attribute 

snapshot_arns: NotRequired[SnapshotArnsList]

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

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

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

snapshot_name instance-attribute 

snapshot_name: NotRequired[String]

The name of a Valkey or Redis OSS snapshot from which to restore data into the new node group (shard). The snapshot status changes to restoring while the new node group (shard) is being created.

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

snapshot_retention_limit instance-attribute 

snapshot_retention_limit: NotRequired[IntegerOptional]

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

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

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

snapshot_window instance-attribute 

snapshot_window: NotRequired[String]

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.

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

tags instance-attribute 

tags: NotRequired[TagList]

A list of tags to be added to this resource.

transit_encryption_enabled instance-attribute 

transit_encryption_enabled: NotRequired[BooleanOptional]

A flag that enables in-transit encryption when set to true.
