Anoop Sam John commented on HBASE-16438:
----------------------------------------
+1 for chunkId being int. That is fine IMO.
We have seqId as a state variable in Cell objects. Now when the cells are
moved to ChunkMap, we lost the cell objects and we have to keep the seqId some
where. On a different way, we could make the seqId 8 bytes also sit after the
Key, Value bytes in the original chunk. But again, this cell meta data also
added to chunks right? So what is the difference?
> 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
