Apache Spark reassigned SPARK-25746:
------------------------------------
Assignee: Apache Spark
> 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
> Assignee: Apache Spark
> Priority: Major
>
> 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.
