Anoop Sam John commented on HBASE-14921:
----------------------------------------
I see..
CellBlockSerialized extends CellBlock.. So 2 impls of the CellBlock. Hmm
good..
If we use the Cell[] way, per Cell we have more overhead. I was having concern
abt this. That is why in 10713, I went with plain byte[] way of serialization
and for speed up of seek used a TreeMap.. Ya if more entries in TreeMap the
speed of seek is more but more overhead. If less entries we have lesser
overhead..
CellBlock makes it possible for whatever way of serialization we need. This is
good. I like it.
