[jira] [Created] (SPARK-31192) Introduce PushProjectThroughLimit

Ali Afroozeh created SPARK-31192:
------------------------------------

             Summary: Introduce PushProjectThroughLimit
                 Key: SPARK-31192
                 URL: https://issues.apache.org/jira/browse/SPARK-31192
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Ali Afroozeh


Currently the {{CollapseProject}} rule does many things: not only it collapses stacked projects, but also pushes down projects into limits, windows, etc. In this PR we factored out rules from {{CollapseProject}} that were pushing projects into limits and introduced a new rule called {{PushProjectThroughLimit.}}
