---------------------------------
cc [~kiszk] Could you help this umbrella ticket?
> Interpreted mode fallback should be implemented for all expressions &
> projections
> ---------------------------------------------------------------------------------

> Key: SPARK-23580
> URL: https://issues.apache.org/jira/browse/SPARK-23580
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Herman van Hovell
> Priority: Major
>
> Spark SQL currently does not support interpreted mode for all expressions and
> projections. This is a problem for scenario's where were code generation does
> not work, or blows past the JVM class limits. We currently cannot gracefully
> fallback.
> This ticket is an umbrella to fix this class of problem in Spark SQL. This
> work can be divided into two main area's:
> - Add interpreted versions for all dataset related expressions.
> - Add an interpreted version of {{GenerateUnsafeProjection}}.
