> Increase spark.sql.codegen.hugeMethodLimit to 65535
> ---------------------------------------------------
>
> Key: SPARK-23267
> URL: https://issues.apache.org/jira/browse/SPARK-23267
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Xiao Li
> Assignee: Xiao Li
> Priority: Blocker
>
> Still saw the performance regression introduced by
> `spark.sql.codegen.hugeMethodLimit` in our internal workloads. There are two
> major issues in the current solution.
> * The size of the complied byte code is not identical to the bytecode size
> of the method. The detection is still not accurate.
> * The bytecode size of a single operator (e.g., `SerializeFromObject`) could
> still exceed 8K limit. We saw the performance regression in such scenario.
> Since it is close to the release of 2.3, we decide to increase it to 64K for
> avoiding the perf regression.
