Sandesh commented on APEXCORE-498:
----------------------------------

Discussed this with [~davidyan] & [~PramodSSImmaneni]. There was a concern that to use this feature properly a lot of effort is required beyond this feature. Existing Operators that use WindowDataManager won't work properly with this feature, they have to be made SavePoint compatible. 

What is your take on this [~thomasWeise] ?

> All checkpoints that happened before the committed window is deleted but the named checkpoints won't be deleted.
