---------------------------------------
Summary: 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
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.
