Jean-Daniel Cryans commented on HBASE-2549:
-------------------------------------------

Do we have enough time do this if 0.90.0 is due for HW? Punt?

> Review Trackers (column, delete, etc) on Trunk after 2248 goes in for 
> correctness and optimal earlying-out

> Once we move to all Scans, the trackers could use a refresh.  There are often 
> times where we return, for example, a MatchCode.SKIP (which just goes to the 
> next KV not including the current one) where we could be sending a more 
> optimal return code like MatchCode.SEEK_NEXT_ROW.
> This is a jira to review all of this code after 2248 goes in.
