    MDEV-20715 : Implement system variable to disallow local GTIDs in Galera · ebb2db59
    Jan Lindström authored
    Added a new wsrep_mode feature DISALLOW_LOCAL_GTID for this.
    Nodes can have GTIDs for local transactions in the following scenarios:
    
    A DDL statement is executed with wsrep_OSU_method=RSU set.
    A DML statement writes to a non-InnoDB table.
    A DML statement writes to an InnoDB table with wsrep_on=OFF set.
    
    If user has set wsrep_mode=DISALLOW_LOCAL_GTID these operations
    produce a error ERROR HY000: Galera replication not supported
