Prasanth Jayachandran reassigned HIVE-20621:
--------------------------------------------
> GetOperationStatus called in resultset.next causing incremental slowness
> ------------------------------------------------------------------------
>
> Key: HIVE-20621
> URL: https://issues.apache.org/jira/browse/HIVE-20621
> Project: Hive
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 4.0.0, 3.2.0
> Environment: Fetching result set for a result cache hit query gets
> slower as more rows are fetched. For fetching 10 row result set it took about
> 900ms but fetching 200 row result set took 8 seconds.
> Reason for this slowness is GetOperationStatus is invoked inside
> resultset.next() and it happens for every row even after operation has
> completed. This is one RPC call per row fetched.
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Major
