MySQL Replication  /  Replication Notes and Tips  /  Replication Features and Issues

4.1 Replication Features and Issues

The following sections provide information about what is supported and what is not in MySQL replication, and about specific issues and situations that may occur when replicating certain statements.

Statement-based replication depends on compatibility at the SQL level between the source and replica. In other words, successful SBR requires that any SQL features used be supported by both the source and the replica servers. For example, if you use a feature on the replication source server that exists in MySQL 5.6 but was removed in MySQL 5.7, errors occur if you replicate to a replica that uses MySQL 5.7. Such incompatibilities also can occur within a release series when using pre-production releases of MySQL.

For this reason, use Generally Available (GA) releases of MySQL for statement-based replication in a production setting, since we do not introduce new SQL statements or change their behavior within a given release series once that series reaches GA release status.

If you are planning to use statement-based replication between MySQL 5.6 and a previous MySQL release series, it is also a good idea to consult the edition of the MySQL Reference Manual corresponding to the earlier release series for information regarding the replication characteristics of that series.

With MySQL's statement-based replication, there may be issues with replicating stored routines or triggers. You can avoid these issues by using MySQL's row-based replication instead. For a detailed list of issues, see Stored Program Binary Logging. For more information about row-based logging and row-based replication, see Binary Logging Formats, and Section 2.2, “Replication Formats”.
