L. C. Hsieh created SPARK-33625:
-----------------------------------

             Summary: Subexpression elimination for whole-stage codegen in Filter
                 Key: SPARK-33625
                 URL: https://issues.apache.org/jira/browse/SPARK-33625
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: L. C. Hsieh
            Assignee: L. C. Hsieh


We made subexpression elimination available for whole-stage codegen in ProjectExec. Another one operator that frequently runs into subexpressions, is Filter. We should also make whole-stage codegen subexpression elimination in FilterExec too.
