MySQL 8.3 Release Notes
BINLOG 'str'
BINLOG is an internal-use statement. It is generated by the mysqlbinlog program as the printable representation of certain events in binary log files. (See Section 6.6.9, “mysqlbinlog — Utility for Processing Binary Log Files”.) The ' value is a base 64-encoded string the that server decodes to determine the data change indicated by the corresponding event.str'
To execute BINLOG statements when applying mysqlbinlog output, a user account requires the BINLOG_ADMIN privilege (or the deprecated SUPER privilege), or the REPLICATION_APPLIER privilege plus the appropriate privileges to execute each log event.
This statement can execute only format description events and row events.
