Extend GTID Binlog Events with Thread Id

    XMLWordPrintable

Details

    Description

      It seems that MySQL 5.6 includes the thread id in the binary log, which can be very handy. It would be nice if MariaDB also did this.

      From MariaDB 10.1.3:

      #150326 12:13:53 server id 1  end_log_pos 407   GTID 0-1-55 trans

      /*!100001 SET @@session.gtid_domain_id=0*//*!*/;
      /*!100001 SET @@session.server_id=1*//*!*/;
      /*!100001 SET @@session.gtid_seq_no=55*//*!*/;
      BEGIN
      /*!*/;
