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

State ments.

State me nt-based replication depends on compatibility atthe SQL level between the master and slave.

In others, successful SBR requires that any SQL features used be supported by both the master and

the slave servers. For example, if you use a feature on the master server that is available only in

MySQL 5.6 (or later), you cannot replicate to a slave that uses MySQL 5.5 (or earlier).

Such incompatibilities also can occur within a release series when using pre-production releases of

MySQL. For example, the SLEEP () [1300] function is available beginning with MySQL 5.0.12. Ifyou

use this function on the master, you cannot replicate to a slave that uses MySQL 5.0.11 or earlier.

For this reason, use Generally Available (GA) releases of MySQL for statement-based replication in a

production setting, sińce we do not introduce newSQL 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 Manuał

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 Section 19.7, “Binary Logging of Stored Programs". For morę information about

row-based logging and row-based replication, see Section 5.2.4.1, "Binary Logging Formats", and

Section 16.1.2, "Replication Formats".
