ATTACHMENT ID: 12940874 - PreCommit-HIVE-Build > 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 > Reporter: Prasanth Jayachandran > Assignee: Prasanth Jayachandran > Priority: Major > Attachments: HIVE-20621.1.patch, HIVE-20621.2.patch > > > 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 (there is also connection > overhead without keepalive). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
