Anoop Sam John commented on HBASE-23279:
----------------------------------------

Ya still good to experiment to know the extra size need because of encoder.  
For same data if NONE have say 100 blocks, how many more blocks we will end up 
having when it is ROW_INDEX_V1 .  Good to know that math. 

> Switch default block encoding to ROW_INDEX_V1

> Currently we set both block encoding and compression to NONE.
> ROW_INDEX_V1 has many advantages and (almost) no disadvantages (the hfiles 
> are slightly larger about 3% or so). I think that would a better default than 
> NONE.
