	PreferredAvailabilityZone *string

	// 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

	// 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

	// Availability Zones. This parameter is only valid if the Engine parameter is

	// arn:aws:s3:::my_bucket/snapshot1.rdb

	// The name of a Redis snapshot from which to restore data into the new node group

	// The number of days for which ElastiCache retains automatic snapshots before
	// deleting them. For example, if you set SnapshotRetentionLimit to 5, a snapshot

	// disabled for this cache cluster).
	SnapshotRetentionLimit *int32

	// 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 .
