Jonathan Gray updated SPARK-15258:
----------------------------------
Attachment: NestedCases.scala
Example code that exhibits the exceptional behaviour
> Nested/Chained case statements generate codegen over 64k exception
> ------------------------------------------------------------------
>
> Key: SPARK-15258
> URL: https://issues.apache.org/jira/browse/SPARK-15258
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.1
> Reporter: Jonathan Gray
> Attachments: NestedCases.scala
>
>
> Nested/Chained case-when expressions generate a codegen goes beyound 64k
> exception.
> A test attached demonstrates this behaviour.
> I'd like to try and fix this but don't really know the best place to start.
> Ideally, I'd like to avoid the codegen fallback as with large volumes this
> hurts performance.
> This is similar(ish) to SPARK-13242 but I'd like to see if there are any
> alternatives to the codegen fallback approach.
