Chetan Mehrotra commented on OAK-3680:
--------------------------------------

Interesting idea. We can possibly save the checkpoint as part of index data. So 
we can see if that has yet not expired then provide a way to trigger indexing 
for that specific index from that checkpoint

> Partial re-index from last known good state

> ATM indexes break (by whatever circumstances) users need to perform a full 
> re-index. Depending on the size off the repository this can take a long time.
> If the user knows that the indexes were in a good state at a certain revision 
> in the past then it would be very useful, if the user could trigger a 
> "partial" re-index where only the content added after a certain revision was 
> updated in the index.
