It indeed would put a rotate event i suggested at relay log head, but not always. if forcely insert a rotate event at relay log head，there would be a redundancy rotate event, which i think not a serious problem though.

Probably not, or if we really want, it should not be hard to only insert the extra rotate event when it is needed.

i can use xid event to detect a partial transaction, but how to detect a partial event without event checksum, because event checksum only contained in Mariadb 5.5+ and MySQL 5.6+

Partial event should be easy to detect, it will just be that you see end-of-file on the relay log file before the event is fully read. - Kristian.
