Jira issue originally created by user romanb:

Setting such a query hint to TRUE should result in all entities being retrieved by that query to be read-only for the purposes of change-tracking. Note that the entities themselves need not necessarily be read-only in general.

This feature is a flush performance tweak that can be used to query for objects but not let the returned objects run through change-tracking on flush. Any other managed objects are tracked as usual so you can do a read-only query for 100 entities and persist a new entity in the same unit of work with optimal flushing performance.

Any news?
Why query hint? What about temporary switching like fetch mode changing via query object?

Any news on this?

I think this is a must have feature. Thanks for all your work.
