Is anyone using PXC for backend database? If so, are you aware of or have you implemented any special DB configuration for use of Drupal 7.x with PXC? i.e. specific parameter/variable settings
We've had several instances of a deadlocking issues involving the drupal semaphore table.
I have seen some mentions of using MyISAM or other engine type for this table, but PXC relies on the use of InnoDB engine for tables for replication.
Any advise and/or insight would be much appreciated.
