As far as I understand, Galera does not support table locking, but what information can be retrieved about the last query?
LOCK/UNLOCK TABLES cannot be supported in master-master replication. Lock functions (GET_LOCK(), RELEASE_LOCK(),…) are not supported.
What about LAST_INSERT_ID()? At some point I read, that the nodes use different auto increment values, but it said nothing whether the last insert id will be returned.
And a related question: In PHP I use the mysql_info function to retrieve the "rows matched" on UPDATE. Is this information expected to be availible in a Galera cluster?
