[jira] [Created] (SPARK-25746) Refactoring ExpressionEncoder

Liang-Chi Hsieh created SPARK-25746:
---------------------------------------

             Summary: Refactoring ExpressionEncoder
                 Key: SPARK-25746
                 URL: https://issues.apache.org/jira/browse/SPARK-25746
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Liang-Chi Hsieh


This is inspired during implementing SPARK-24762. For now ScalaReflection needs to consider how ExpressionEncoder uses generated serializers and deserializers. And ExpressionEncoder has a weird flat flag. After discussion with [~cloud_fan], it seems to be better to refactor ExpressionEncoder. It should make SPARK-24762 easier to do.
