Matt Corgan commented on HBASE-7233:
------------------------------------
I like it. Nice and simple.
What are your thoughts on BasicCellEncoder vs KeyValueEncoder? Are you
introducing the new "BasicCell" format because it's easier for a non-java
client to decode?
KeyValueEncoder appears faster in this benchmark because the serialization is
less granular, but I think that will become irrelevant over time if we get the
Cell interface all the way up the read path. It's faster now because you know
the input cell is KeyValue so can just cast. If you don't know the input Cell
implementation, you'd have to append each KeyValue field separately.
Would probably be good to include BasicCellEncoder and KeyValue encoder just to
make sure that the necessary abstractions are in place to add future encodings.
Later on, my guess is one of the delta-style encoders will be best for java
client RPC.
