Yes, transactions are used and AFAIK, transaction level is set to READ COMMITED.

You would benefit from setting the logging level to TRACE to get more insight 
as most of the logging at the DAO layer is set to TRACE.

Subject: question about JDBC and mysql

Hi List.

Does cloudstack uses transactions when writing to mysql ? i happen to see
data and soon enough disappears , like if i would be using READ_UNCOMMITTED.

The whole thing is that on a snapshot failure , the snapshot ID didn't get
status of "Error" it simply vanished from the snapshots table .. but we saw
the record while the snapshot was in progress.

Thanks!
