CreateGlobalDistributeCache - ApsaraDB for Redis - Alibaba Cloud Documentation Center

Converts an existing ApsaraDB for Redis instance to the first child instance of a distributed ApsaraDB for Redis instance.

Operation description

You cannot directly create a distributed instance. If you require a distributed instance, you must call this operation to convert an existing instance to the first child instance of the distributed instance. After the instance is converted, the distributed instance is created. Before you call this operation, make sure that the following requirements are met:

A DRAM-based instance of Enhanced Edition is used.
If the existing instance is a cluster instance, the direct connection mode must be disabled for the instance. For more information, see Release a private endpoint.

Note You can also call the CreateInstance operation to create an instance that is specified as the first child instance of a distributed instance. After the child instance is created, the distributed instance to which the child instance belongs is created.
