DB Tsai created SPARK-24890:
-------------------------------

             Summary: Short circuiting the `if` condition when `trueValue` and `falseValue` are the same
                 Key: SPARK-24890
                 URL: https://issues.apache.org/jira/browse/SPARK-24890
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: DB Tsai


When `trueValue` and `falseValue` are semantic equivalence, the condition expression in `if` can be removed to avoid extra computation in runtime.
