------------------------------------
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.}}
