   > @roodkcab It looks like `MySQLXARecoverStatement` has not been handled. This could cause non-consistent data when the transaction manager is doing the crash recovery. Also you skip the `XAEnd` and `XAPrepare`, and I think this could not be compatiable with XA protocol.
   
   End and Prepare is handled by ShardingSphereTransactionManager(Atomikos), which should be skipped here. For broadcasting sqls to backend database, I think it's better to implement jdbc and proxy in the same way.
