part1 (was: HiveServer2: Improve HiveServer2 JDBC/ODBC ResultSet performance)
> HiveServer2: Improve HiveServer2 JDBC/ODBC ResultSet performance - part1
> ------------------------------------------------------------------------
>
> Key: HIVE-12427
> URL: https://issues.apache.org/jira/browse/HIVE-12427
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2, JDBC, ODBC
> Reporter: Vaibhav Gumashta
>
> The current implementation does a lot of CPU intensive work in HiveServer2.
> It deserializes the temporary results written to disk and also serializes
> the results into thrift objects in HS2. This adds to the latency of fetching
> results via HS2. Doing that work in the task nodes would get that work done
> in parallel and scale it, thereby reducing the time it takes to retrieve
> large results.
