Currently we create several loaders following a certain algorithm Why don't we create a single loader of batch-size and duplicate ids in the in clause to match unfilled parameters batch-size = 20 uninitialized proxies 17 current algorithm select * from Table where id in (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) select * from Table where id in (11, 12, 13, 14, 15, 16, 17) current algorithm select * from Table where id in (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 17, 17, 17) This would reduce the memory footprint and reduce the prepared statement pool needed This case is a sample but it shines when people set up a batch-size of 100 since the number of queries triggered can drop from 5 to 1 query for 98 uninitialized proxies _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
