ATTACHMENT ID: 12774231 - PreCommit-HIVE-TRUNK-Build > Add mysql-style LIMIT support to Hive, or improve ROW_NUMBER performance-wise > ----------------------------------------------------------------------------- > > Key: HIVE-11531 > URL: https://issues.apache.org/jira/browse/HIVE-11531 > Project: Hive > Issue Type: Improvement > Reporter: Sergey Shelukhin > Assignee: Hui Zheng > Attachments: HIVE-11531.02.patch, HIVE-11531.WIP.1.patch, > HIVE-11531.WIP.2.patch, HIVE-11531.patch > > > For any UIs that involve pagination, it is useful to issue queries in the > form SELECT ... LIMIT X,Y where X,Y are coordinates inside the result to be > paginated (which can be extremely large by itself). At present, ROW_NUMBER > can be used to achieve this effect, but optimizations for LIMIT such as TopN > in ReduceSink do not apply to ROW_NUMBER. We can add first class support for > "skip" to existing limit, or improve ROW_NUMBER for better performance -- This message was sent by Atlassian JIRA (v6.3.4#6332)
