Harish Butani commented on HIVE-896: ------------------------------------ Hi, Yes, I have been developing SQL Windowing on top of Hive(https://github.com/hbutani/SQLWindowing/wiki). Users can intersperse Hive Queries with Windowing Clauses and Table functions. Users can use this from a CLI (hive --service windowingCLI) or via a Query API. The hope is to provide Users: - Windowing Clauses and Table functions as a simple extension to HQL - overtime to fold the implementation into the Hive code base with hopefully minimal impact to the User experience. Here are some thoughts on how to fold this functionality into Hive: https://github.com/hbutani/SQLWindowing/wiki/MoveToHive Any thoughts/comments/suggestions greatly welcomed. regards, Harish Butani. > Add LEAD/LAG/FIRST/LAST analytical windowing functions to Hive. > --------------------------------------------------------------- > > Key: HIVE-896 > URL: https://issues.apache.org/jira/browse/HIVE-896 > Project: Hive > Issue Type: New Feature > Components: OLAP, UDF > Reporter: Amr Awadallah > Priority: Minor > > Windowing functions are very useful for click stream processing and similar > time-series/sliding-window analytics. > More details at: > http://download-west.oracle.com/docs/cd/B13789_01/server.101/b10736/analysis.htm#i1006709 > http://download-west.oracle.com/docs/cd/B13789_01/server.101/b10736/analysis.htm#i1007059 > http://download-west.oracle.com/docs/cd/B13789_01/server.101/b10736/analysis.htm#i1007032 > -- amr -- This message is automatically generated by JIRA.
