Nick Dimiduk commented on HBASE-10573:
--------------------------------------

I'm curious about the decision to use Netty's classes here. In particular, I 
believe the reason [~mcorgan] introduced the ByteRange interface was because 
none of the existing "byte buffer" concepts allowed for buffer re-use. The 
concern being for excessive GC during compactions. I looked at Netty's ByteBuf 
a while back and found it didn't support instance reuse, thus was insufficient 
for his requirement. Did I miss something?
