how to skip mysqlbinlog reading error – ERROR: Found out of order GTID

main menu
MariaDB select gtid_strict_mode

When trying to read the MariaDB binlog files, the reading may be interrupted with an error message, and the reading will stop:

ERROR: Found out of order GTID. Got 0-3-855835750755 after 0-1-855835750756

Some positions are shown but after 24 lines of 1236849 file, the mariadb-binlog / mysqlbinlog program interrupts with an error.

It turns out the problem is that the mariadb-binlog / mysqlbinlog reads the binlog files with GTID strict mode, because it is enabled by default! But the servers may have turned it off, so the binlog files are in the wrong format for the strict mode reading. The mode to read the binlog files should be the same as the MySQL / MariaDB server mode that created the binlog files.

When the binlog files are generated with gtid_strict_mode = 0 the “–skip-gtid-strict-mode” option should be used with mariadb-binlog / mysqlbinlog to read the binlog files without errors. More on gtid_strict_mode for MariaDB –
