Vikas Saurabh commented on OAK-6787:
------------------------------------

Patch lgtm.
bq. was thinking to use this when NodeStore is of type Clusterable
I'm guessing you are saying that seg-store can do a a very fast sub-tree 
deletion!? If so, yes, I think that would be useful - I guess that check would 
happen at the wiring end though, right?

> PropertyIndexCleaner currently remove the property index bucket in a single 
> remove. This would work fine with SegmentNodeStore but would cause issue with 
> DocumentNodeStore where it would result in a one large commit.
> To avoid this scenario we should implement recursive delete. This approach 
> would only be used if NodeStore implements Clusterable
