Using data tiering

When creating a cluster, you use data tiering by selecting a node type from the r6gd family, such as db.r6gd.xlarge. Selecting that node type automatically enables data tiering.

For more information on creating a cluster, see Step 2: Create a cluster.

When creating a cluster using the AWS CLI, you use data tiering by selecting a node type from the r6gd family, such as db.r6gd.xlarge and setting the --data-tiering parameter.

You cannot opt out of data tiering when selecting a node type from the r6gd family. If you set the --no-data-tiering parameter, the operation will fail.

For Linux, macOS, or Unix:

aws memorydb create-cluster \
   --cluster-name my-cluster \
   --node-type db.r6gd.xlarge \
   --engine valkey  \
   --acl-name my-acl \
   --subnet-group my-sg \
   --data-tiering

For Windows:

aws memorydb create-cluster ^
   --cluster-name my-cluster ^
   --node-type db.r6gd.xlarge ^
   --engine valkey ^
   --acl-name my-acl ^
   --subnet-group my-sg
   --data-tiering

After running this operation, you will see a response similar to the following:
