Vaibhav Gumashta updated HIVE-12428:
------------------------------------
Description: Once HIVE-12049 is complete, we will have an option on HS2
side to avoid paying the deserialization penalty and simple stream batches of
rows on the wire which the *DBC driver can appropriately interpret. This can be
done by changing the FetchOperator such that when it has the thrift formatted
row sets available, it uses the fastpath. For queries where tasks don't write
thrift rowsets, the current implementation will suffice.
> Provide an option for HiveServer2 to stream serialized thrift results when
> they are available
