-----------------------------
Summary: Redo the hfile index length optimization so cell-based
rather than serialized KV key
Key: HBASE-12313
URL: https://issues.apache.org/jira/browse/HBASE-12313
Project: HBase
Issue Type: Sub-task
Reporter: stack
Assignee: stack
Trying to remove API that returns the 'key' of a KV serialized into a byte
array is thorny.
I tried to move over the first and last key serializations and the hfile index
entries to be cell but patch was turning massive. Here is a smaller patch that
just redoes the optimization that tries to find 'short' midpoints between last
key of last block and first key of next block so it is Cell-based rather than
byte array based (presuming Keys serialized in a certain way). Adds unit tests
which we didn't have before.
Also remove CellKey. Not needed... at least not yet. Its just utility for
toString.
