CreateGlobalDistributeCache - Tair (Redis® OSS-Compatible)

Converts an existing Tair DRAM-based classic instance to the first child instance of a distributed instance.

Operation description

You can call this operation to convert an existing instance to the first child instance of a 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:

The instance that you want to convert must be a Tair DRAM-based instance that uses the classic deployment mode.
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.
