The Ultimate Guide to High Availability with MariaDB

ANNOTATE_ROWS_EVENT

ANNOTATE_ROWS_EVENT events accompany row events and describe the query which caused the row event.

You can enable this with --binlog-annotate-row-events (default on from MariaDB 10.2.4).

In the binary log, each Annotate_rows event precedes the corresponding Table map event.

For additional information refer to the annotate_rows_log_event documentation.

Note: the master server sends ANNOTATE_ROWS_EVENT events only if the Slave server connects with the BINLOG_SEND_ANNOTATE_ROWS_EVENT flag (value is 2) in the COM_BINLOG_DUMP Slave Registration phase.

  • Event Type is 160 (0xa0)
