Lars Hofhansl updated HBASE-14315:
----------------------------------
Description:
Another one of my micro optimizations.
In StoreScanner.next(...) we can actually save a call to KeyValueHeap.peek,
which in my runs of scan heavy loads shows up at top.
Based on the run and data this can safe between 3 and 10% of runtime.
