> -------------------
> If the do Query variant can be implemented with cursor, then it helps with any heavy lifting (bulk processing) with entity processor. That really helps.
> If permitted I can contribute the fix. Currently I am using 4.10 and see the performance issues and planning the work around. If the cursor is available then it really helps.
