ramkrishna.s.vasudevan commented on HBASE-16438:
------------------------------------------------
IMHO the whole new cell should come only when we have CellChunkMap. The cell in
the current patch is fine as it does not add much overhead except for adding an
entry in the ChunkID map. But the new cell where seqId has to be embedded in
the cell has to happen only while moving over to CellChunk representation. With
default memstore case it is unwanted.
> Create a cell type so that chunk id is embedded in it

> For CellChunkMap we may need a cell such that the chunk out of which it was
> created, the id of the chunk be embedded in it so that when doing flattening
> we can use the chunk id as a meta data. More details will follow once the
> initial tasks are completed.
> Why we need to embed the chunkid in the Cell is described by [~anastas] in
> this remark over in parent issue
