Lars Hofhansl commented on HBASE-5520:
--------------------------------------
Generally it would be very useful for coprocessors to have this ability!
After looking at the discussion here (the restrictions imposed on what KVs one
can passed - previous ones, row only, column family needs to be ignored, etc)
we just need to be careful how we add this.
For this specific issue it would be nice to get some comparative performance
numbers between this and filters. Maybe we're missing a level of abstraction...?
