What is the format of the binlog log? for this question, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The units recorded in the binlog log are events, not sql statements.

Format description event records the server version number and binary version number. A log ends with a Rotate event that tells the log the location of the next log.

Table_map event records the mapping of the table, what the columns of the table are, what the type of columns are, and the source data information. The contents stored in table_map can be viewed by mysqlbinlog. For example, the first column is 4 updated to 24 table_map type, all stored in it.

You can't do without table_map.

Query-- > Table_map-- > Update_rows-- > Xid

Imagine what would happen if there was no table_map and only update_rows. No, no metadata information could be found.
