MySQL Cluster-opracowanie

MySQL Cluster. The default binary logging format in all MySQL Cluster NDB 7.3 releases is MIXED.
You should note that MySQL Cluster Replication always uses row-based replication, and that the
NDB storage engine is incompatible with statement-based replication. See Section 17.6.2, “General
Requirements for MySQL Cluster Replication”, for more information.
When using MIXED format, the binary logging format is determined in part by the storage engine being
used and the statement being executed. For more information on mixed-format logging and the rules
governing the support of different logging formats, see Section 5.2.4.3, “Mixed Binary Logging Format”.
The logging format in a running MySQL server is controlled by setting the binlog_format [2047]
server system variable. This variable can be set with session or global scope. The rules governing
when and how the new setting takes effect are the same as for other MySQL server system variables—
setting the variable for the current session lasts only until the end of that session, and the change is not
visible to other sessions; setting the variable globally requires a restart of the server to take effect. For
more information, see Section 13.7.4, “SET Syntax”.
There are conditions under which you cannot change the binary logging format at runtime or doing so
causes replication to fail. See Section 5.2.4.2, “Setting The Binary Log Format”.
You must have the SUPER [776] privilege to set either the global or session binlog_format [2047]
value.
The statement-based and row-based replication formats have different issues and limitations. For a
comparison of their relative advantages and disadvantages, see Section 16.1.2.1, “Advantages and
Disadvantages of Statement-Based and Row-Based Replication”.
With statement-based replication, you may encounter issues with replicating stored routines or
triggers. You can avoid these issues by using row-based replication instead. For more information, see
Section 19.7, “Binary Logging of Stored Programs”.
