[jira] [Created] (SPARK-8641) Native Spark Window Functions

Herman van Hovell tot Westerflier created SPARK-8641:
--------------------------------------------------------

             Summary: Native Spark Window Functions
                 Key: SPARK-8641
                 URL: https://issues.apache.org/jira/browse/SPARK-8641
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 1.5.0
            Reporter: Herman van Hovell tot Westerflier


The current Window implementation uses Hive UDAFs for all aggregation operations. In this ticket we will move to this functionality to Native Spark Expressions.

A PR will follow as soon as SPARK-8639 gets in.
