Reynold Xin created SPARK-17844:
-----------------------------------
Summary: DataFrame API should simplify defining frame boundaries
without partitioning/ordering
Key: SPARK-17844
URL: https://issues.apache.org/jira/browse/SPARK-17844
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Reynold Xin
Assignee: Reynold Xin
When I was creating the example code for SPARK-10496, I realized it was pretty
convoluted to define the frame boundaries for window functions when there is no
partition column or ordering column. The reason is that we don't provide a way
to create a WindowSpec directly with the frame boundaries. We can trivially
improve this by adding rowsBetween and rangeBetween to Window object.
