Ziyang Zhao updated HIVE-12427: ------------------------------- Assignee: (was: Ziyang Zhao) > HiveServer2: Improve HiveServer2 JDBC/ODBC ResultSet performance > ---------------------------------------------------------------- > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
