> 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.
