Hello,
We have a database containing PostGIS MAP data, it is accessed mainly
via JDBC. There are multiple simultaneous read-only connections taken
from the JBoss connection pooling, and there usually are no active
writers. We use connection.setReadOnly(true).
Now my question is what is best performance-wise, if it does make any
difference at all:
Having autocommit on or off? (I presume "off")
Using commit or rollback?
Committing / rolling back occasionally (e. G. when returning the
connection to the pool) or not at all (until the pool closes the
connection)?
Thanks,
Markus
