Fake ROTATE_EVENT
When a slave server connects to a MariaDB master server, the first binlog event sent is Fake ROTATE_EVENT
. This event is similar to ROTATE_EVENT, but it's artificial and its purpose is to tell the replica server which the binlog file name of the master is.
This matters when the replica connects with the GTID option (no filename is given) or when using file and pos with empty file name (usually file='' and pos = 4).
The Event Type is ROTATE_EVENT
(0x4
).
