START GROUP_REPLICATION

Starts Group Replication on this server instance. This statement requires the SUPER privilege. If super_read_only=ON and the member should join as a primary, super_read_only is set to OFF once Group Replication successfully starts.

A server that participates in a group in single-primary mode should use skip_replica_start=ON. Otherwise, the server is not allowed to join a group as a secondary.
