The reason for this parameter is because all events generated by the CDC code contain the database image before and after the change. There are three supported formats for binary log events:. Therefore the choice between row-based replication (RBR) or statement-based replication (SBR) depends on your application and environment. You can exercise control over the binary log format in two ways: To control the log format that the server uses for an entire test run, you can pass options to mysql-test If a server is running with binlog_format set to MIXED and you want it to be possible to use mysqlbinlog with the --database option, A “ login path ” is an option group containing options that specify which MySQL server to connect to and which account to authenticate as.
