20.9.2 Group Replication Status Variables

MySQL 8.0 supports one status variable providing information about Group Replication. This variable is described here:

• group_replication_primary_member

  Shows the primary member's UUID when the group is operating in single-primary mode. If the group is operating in multi-primary mode, shows an empty string.

  Warning

  The group_replication_primary_member status variable has been deprecated and is scheduled to be removed in a future version.

  See Section 20.1.3.1.2, “Finding the Primary”.
