>
> JDBC Master/Slave doesn't work properly for mysql cluster when the master and
> slave brokers are using different MYSQL frontends as would be required in a
> HA setup. The code currently locks the database using a TABLE lock which are
> not cluster wide in mysql.
> http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-limitations-multiple-nodes.html
> The default code path uses a SELECT FOR UPDATE to get a lock. This is
> supported in mysql cluster.
> The attached patch works for me.
