      The CellChunkMap is very dense index for Memstore ImmutableSegment and the only one that can be taken off-heap. However, CellChunkMap works on-heap as well. The coding of the entire flow of working with CellChunkMap is not yet finished, thus CellChunkMap is disabled for usage so far. The continuation is done under HBASE-18232.

    Description

      The CellChunkMap helps to create a new type of ImmutableSegment, where the index (CellSet's delegatee) is going to be CellChunkMap. No big cells or upserted cells are going to be supported here.
