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.
