------------------------------------------------
bq. 3. C was reused from pool and returned to the user once again
At this point of time we again add it back to the mapping. See
ChunkCreator#getChunk()
{code}
// put this chunk into the chunkIdMap
this.chunkIdMap.put(chunk.getId(), new SoftReference<>(chunk));
// now we need to actually do the expensive memory allocation step in case
of a new chunk,
// else only the offset is set to the beginning of the chunk to accept
allocations
chunk.init();
{code}
> Connect CellChunkMap to be used for flattening in CompactingMemStore

> 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.
