Anastasia Braginsky commented on HBASE-14921:
---------------------------------------------
And here we go!!!
Please take a look on the attached patch of CellFlatMaps connected to recent
version of CompactingMemStore. The CellSet can now be implemented also as
CellArrayMap or CellChunkMap, thus influencing the ImmutableSegment holding
that CellSet.
For more explanations please also take a look on the attached "Introduction to
New Flat and Compact MemStore" document. There are still some completions and
improvements to be done, but please take a look to get the idea. Enjoy!
