Hibernate Batch Fetch style recommendations

Hibernate ORM

Hello,

thanks! Some additional feedback to try to prove my point… this is the memory dump taken from my application before upgrading to Hibernate 5.3:

and this is the heap after the upgrade (the same of my previous post):

hb2

Please note the difference between the retained size of the SingleTableEntityPersister instances. In particular, the retained size of each SingleTableEntityPersister is coming from a map where each entry references the mentioned LegacyBatchingEntityLoader.
