Hakim resolved DRILL-4270. ------------------------------------- Resolution: Fixed Fixed in 3d0b4b0 > Create a separate WindowFramer that supports the FRAME clause > ------------------------------------------------------------- > > Key: DRILL-4270 > URL: https://issues.apache.org/jira/browse/DRILL-4270 > Project: Apache Drill > Issue Type: Sub-task > Components: Execution - Relational Operators > Affects Versions: 1.5.0 > Reporter: Deneche A. Hakim > Assignee: Deneche A. Hakim > Fix For: Future > > > Currently most the window functions logic is handled by DefaultFrameTemplate. > Create a separate CustomFrameTemplate that handles the FRAME clause, this > should make the code in both classes more focused and will make it easier for > us to add support for the FRAME clause. > Aggregations, FIRST_VALUE and LAST_VALUE will be handled by > CustomFrameTemplate, and all remaining window functions (Ranking, ROW_NUMBER, > LEAD and LAG) will be handled by DefaultFrameTemplate. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
