Problem setting connection to readOnly with ReplicationDriver, c3p0 & hibernate
Hi,
I'm using c3p0 and hibernate with java and ReplicationDriver. I have one master and one slave. On certain read-only queries, I want to hit the slave instead of the master. I do this by session.connection().setReadOnly(true) right before I do beginTransaction().
My problem is with a query like this on a read-only connection hitting the slave:
select SQL_CALC_FOUND_ROWS distinct col1 from table1 where ...
The query results return FOUND_ROWS = 1, but the result list has size 0. Stopping the app and looking at the slave then, I see that there should be no results. Although I'm having trouble tracking down why FOUND_ROWS returns 1.
The problem seems to go away when I don't use c3p0. I haven't had too much luck anywhere else and I know this is not a c3p0 forum, but has anyone seen anything like this with ReplicationDriver? Or any tips on how I can debug it further?
Thanks.
