Hi all, There are four higher order functions in our backlog:
- https://issues.apache.org/jira/browse/SPARK-41235 - https://issues.apache.org/jira/browse/SPARK-41234 - https://issues.apache.org/jira/browse/SPARK-41233 - https://issues.apache.org/jira/browse/SPARK-41232 Would be a great chance for new contributors to understand and get into Catalyst optimizer and Spark SQL. Any help on these tickets would be much appreciated.
