[jira] [Created] (OAK-3380) Property index pruning should happen asynchronously

Vikas Saurabh created OAK-3380:
----------------------------------

             Summary: Property index pruning should happen asynchronously
                 Key: OAK-3380
                 URL: https://issues.apache.org/jira/browse/OAK-3380
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: query
    Affects Versions: 1.3.5
            Reporter: Vikas Saurabh
            Priority: Minor


Following up on this (a relatively old) thread \[1], we should do pruning of property index structure asynchronously. The thread was never concluded, here are a couple of ideas picked from the thread:
* Move pruning to an async thread
* Throttle pruning i.e. prune only once in a while
** I'm not sure how that would work though -- an unpruned part would remain as is until another index happens on that path.

Once we can move pruning to some async thread (reducing concurrent updates), OAK-2673 + OAK-2929 can take care of add-add conflicts.
