currently, the only way to get the GTID of the last transaction is by enabling session_track_gtids ([1]) and using the 2 following Connector functions:

- mysql_session_track_get_first ([2])
- and mysql_session_track_get_next ([3]).

[1]: https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_session_track_...

[2]: https://dev.mysql.com/doc/refman/5.7/en/mysql-session-track-get-first.html

[3]: https://dev.mysql.com/doc/refman/5.7/en/mysql-session-track-get-next.html

So this means that for getting the last transaction GTID, one needs the right connector and a driver which support this feature.

To remove those constraints, would you please consider exposing the last transaction GTID in a session variable ?

Many thanks,
