---------------------------------
Summary: Subexpression elimination support shortcut conditional
expression
Key: SPARK-42815
URL: https://issues.apache.org/jira/browse/SPARK-42815
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.5.0
Reporter: XiDuo You
The subexpression in conditional expression may not need to eval even if it
appears more than once.
e.g., `if(or(a, and(b, b)))`, the expression `b` would be skipped if `a` is
true.
