ramkrishna.s.vasudevan commented on HBASE-16421:
------------------------------------------------

I will give a patch for the chunk id in the Cell's bytebuffer.
bq.The scans on top of the CellChunkMap
Started doing it . Will report back tomorrow with some reports.
I can see that flush is generated lot of garbage for sure. But impact on scan not pretty much
sure how to measure it but I can see how is the Gc impact in a mixed read write work load.
