MySQL 5.6 introduced a new feature called GTID (Global Transaction IDentifier) support in Replication. For every transaction that is committed on to the server, a GTID of the format :
server_uuid:transaction_id is written into the master's binary log.
This offers the following advantages:
Very helpful to set up a slave and create a replication setup.
User need not worry about fetching the master's binlog filename and position in the “CHANGE MASTER TO” command which is used to synchronise the slave with the master.
