Anoop Sam John commented on HBASE-13448:
----------------------------------------

We can actually instantiate standalone HRegion (we do in tests).  May be need 
to create a stub for the HFileReader which just returns an in memory HFile 
block?  Will see more. That test will be good to do JMH kind of micro benchmark 
but E2E scan flow. (Atleast from HRegion onward)

> New Cell implementation with cached component offsets/lengths
