I've not used it yet, but my impression is that you can use
PreparedStatements (in a loop typically), often surrounded by jdbc
transaction commit so each statement doesn't run in its own
transactions, do an addBatch and then submit that so all of the
statements are executed by the server as a group. So in this case, yes,
they should be independent of each other.
