Prasanth Jayachandran commented on HIVE-9049:
---------------------------------------------
I am fine with making it configurable and keeping it off by default as it
breaks compatibility. I can put up a patch for it in sometime.
> Metastore should use TCompactProtocol as opposed to TBinaryProtocol

> Hive metastore server/client uses TBinaryProtocol. Although binary protocol
> is better than simple text/json protocol it is not as effective as
> TCompactProtocol. TCompactProtocol is typically more efficient in terms of
> space and processing (CPU). As seen from this benchmark TCompactProtocol is
> better in almost all aspect when compared to TBinaryProtocol
