Hi! I am looking at http://kb.askmonty.org/en/annotate_rows_log_event. This feature is only present in 5.3. However, the output there shows: master> SHOW BINLOG EVENTS IN 'master-bin.000001'; +-------------------+------+---------------+-----------+-------------+---------------------------------------------------+ | Log_name | Pos | Event_type | Server_id | End_log_pos | Info | +-------------------+------+---------------+-----------+-------------+---------------------------------------------------+ | master-bin.000001 | 4 | Format_desc | 100 | 240 | Server ver: 5.1.44-debug-log, Binlog ver: 4 | Note that the version is 5.1.44! THis is confusing. How did we get this output? Is it because binlog annotation was a patch against 5.1 at some point?
