/ MySQL Server Administration / MySQL Server Logs / The Binary Log / Setting The Binary Log Format 5.4.4.2 Setting The Binary Log Format You can select the binary logging format explicitly by starting the MySQL server with --binlog-format= type. A session that makes many small changes to the database might want to use row-based logging. A session that performs updates that match many rows in the WHERE clause might want to use statement-based logging because it will be more efficient to log a few statements than many rows. Some statements require a lot of execution time on the master, but result in just a few rows being modified. Replication capabilities in MySQL originally were based on propagation of SQL statements from master to slave. This is called statement-based logging.You can cause this format to be used by starting the server with --binlog-format=STATEMENT. In row-based logging, the master writes events to the binary log that indicate how individual table rows are affected. In MySQL 5.6, the default binary logging format is STATEMENT. The logging format also can be switched at runtime. Set the global value of the binlog_format system variable to specify the format for clients that connect subsequent to the change. Status of this subsection: Complete but not reviewed 2009-10-21. The binlog is organized as a linear sequence of events.An SQL query that modifies the database will generate one or more events and append them to the binlog.

If the mysql database is edited directly, logging is performed as expected according to the binlog_format.

There's no discrepancy. RDS, being a managed service, does not enable every possible configurable value for every configuration parameter. The architects of RDS chose not to make STATEMENT available as an option for BINLOG_FORMAT, presumably, because they recognize the fact that it has many limitations in a replication environment. Not all statements which modify data such as INSERT,.

What is the safest way to switch the binlog format at runtime? Ask Question Asked 8 years, 4 months ago. Active 8 years, 3 months ago. Since a binlog will have a specific format at the moment you do this, you may decide not to gamble with the two formats together although MySQL eh Oracle [still can't roll off my tongue]. But, if you check the online MySQL manual, it says: Note Each MySQL Server can set its own and only its own binary logging format true whether binlog_format is set with global or session scope. This means that changing the logging format on a replication master does not cause a slave to change its logging format to match. I have mysql binlog enabled in row format. I am using mysqlbinlog to parse binlog file. I am using this command: mysqlbinlog --base64-output=decode-rows -vv./mysql-bin.000004 This command returns sql statements that I have to parse to generate json. I used pymysqlreplication module in python but it doesn't read from binlog file. ★ binlog_format 종류 및 차이.

Giuseppe, Thanks for reporting this, but I don't think this is something specific of GTID, nor specific to 5.6, nor a bug at all. However, I am also assuming that you are running the slave SQL thread with binlog_format=STATEMENT. Description: A user can change the binlog format for the session SUPER is required for global but not for session. If e.g. the DBA wants to use some tricks that are only possible using RBL, then a user can now change the log himself to STATEMENT mode and screw up things for the DBA.
