--------------------------------------
Yes, can you try and see if it works?
> oom exception occurred during code generation due to a large number of case
> when branches

> Key: SPARK-36903
> URL: https://issues.apache.org/jira/browse/SPARK-36903
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.0.1
> Reporter: JacobZheng
> Priority: Major
>
> I have a spark task that contains many case when branches. When I run it, the
> driver throws an oom exception in the codegen phase. What I expect is if it
> is possible to detect or limit it in the codegen phase to avoid this.
>
> I see that spark 2.2 has a configuration item
> spark.sql.codegen.maxCaseBranches. would it help my situation if I try to add
> this limit back?
