There is a one-to-one mapping between all transactions and all GTIDs.

A GTID is represented as a pair of coordinates, separated by a colon character (:):

GTID = source_id:transaction_id

The source_id option identifies the originating server. Normally, the server's server_uuid option is used for this purpose. The transaction_id option is a sequence number determined by the order in which the transaction was committed on this server. For example, the first transaction to be committed has 1 as its transaction_id, and the tenth transaction to be committed on the same originating server is assigned a transaction_id of 10.
