Yesterday I've put some new features into the ansible's mysql_replication module, because we are planning to move to GTID based replication from the good old binlog position based one, and the module wasn't aware of.
This parameter can be either 0 or 1, defaults to 0. If set to 1 the replication will be threaded as GTID based replication.
This parameter threats the warnings, because MySQL 5.6 complaints a lot more than the previous versions. (For example, if the replication is not encrypted with SSL/TLS.) This could break our playbooks, so you can set it to all, warnings, none (defaults none). Speaks for itself, all means all warnings/errors will be shown, if warnings set, then only the errors will be shown, and the warnings supressed, and if none then that means, every message will be show up as-is.
If you need it, and you don't want to wait until it is merged and released, you can dowload it from my GitHub repository.
