------------------------------------

             Summary: Pass blocks of KVs from HFile scanner to the StoreFileScanner and up
                 Key: HBASE-9440
                 URL: https://issues.apache.org/jira/browse/HBASE-9440
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl


Currently we read KVs from an HFileScanner one-by-one and pass them up the scanner/heap tree.
Many time the ranges of KVs retrieved from StoreFileScanner (by StoreScanners) and HFileScanner
(by StoreFileScanner) will be non-overlapping. If chunks of KVs do not overlap we can sort
entire chunks just by comparing the start/end key of the chunk. Only if chunks are overlapping
do we need to sort KV by KV as we do now.

I have no patch, but I wanted to float this idea.
