[jira] [Created] (SPARK-45607) Collapse repartition with project

Wan Kun created SPARK-45607:
-------------------------------

             Summary: Collapse repartition with project
                 Key: SPARK-45607
                 URL: https://issues.apache.org/jira/browse/SPARK-45607
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 4.0.0
            Reporter: Wan Kun


We can collapse two repartition operators with a project between them.

For example:

df.repartition($"a").select($"a", $"b", $"a" + $"b").repartition($"b")

is same to

df.select($"a", $"b", $"a" + $"b").repartition($"b")
