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:
