The Amazon Resource Name (ARN) of the SNS notification topic
SnsTopicStatus (string) --
The SNS topic must be in Active status to receive notifications

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.
SnapshotWindow (string) --
The daily time range (in UTC) during which MemoryDB begins taking a daily snapshot of your shard. Example: 05:00-09:00 If you do not specify this parameter, MemoryDB automatically chooses an appropriate time range.
ACLName (string) --
The name of the Access Control List associated with this cluster.
AutoMinorVersionUpgrade (boolean) --
When set to true, the cluster will automatically receive minor engine version upgrades after launch.
DataTiering (string) --
Enables data tiering. Data tiering is only supported for clusters using the r6gd node type. This parameter must be set when using r6gd nodes. For more information, see Data tiering.
