------------------------------------
Summary: Refactor SortOrder class to allow multiple childrens
Key: SPARK-33503
URL: https://issues.apache.org/jira/browse/SPARK-33503
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.1
Reporter: Prakhar Jain
Currently the SortOrder is a UnaryExpression with only one child. It contains a
field "sameOrderExpression" that needs some special handling as done in
[https://github.com/apache/spark/pull/30302] .
One of the suggestion in
[https://github.com/apache/spark/pull/30302#discussion_r526104333] is to make
sameOrderExpression as children of SortOrder.
