Anastasia Braginsky commented on HBASE-16438:
---------------------------------------------
Guys,
I think we are all confused. What I am talking about Cell-reference
(chunkID+length+offset) need to be only part of CellChunkMap it is accessed
only by CellChunkMap (written and read only by CellChunkMap). We can even not
to create any new cell type. CellChunkMap when created is going to write
(chunkID+length+offset) per cell in its index-chunk. Later when it is asked to
return a Cell, CellChunkMap is going to read the relevant cell-reference from
the chunk-index, then access the data-chunk and read the "true" cell data
(key,value,seqID, etc.) and return it to anyone who needs.
What is the problem with that?

> 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
