-----------------------------------
Labels: pull-request-available (was: )
> Split generated methods can still be too large to be JIT-compiled
> -----------------------------------------------------------------
>
> Key: FLINK-41382
> URL: https://issues.apache.org/jira/browse/FLINK-41382
> Project: Flink
> Issue Type: Technical Debt
> Components: Table SQL / Runtime
> Reporter: Sergey Nuyanzin
> Assignee: Sergey Nuyanzin
> Priority: Major
> Labels: pull-request-available
>
> Generated code can contain very long methods. The code splitter moves their
> statements into smaller methods. The original method then calls these smaller
> methods one after another.
> This list of calls is not split. With very large generated code, it can
> contain thousands of calls. The method is then too large for the JVM to
> JIT-compile, so it runs in the interpreter for every record.
> Example: for a CASE with 10000 branches(FLINK-41380), this method took about
> 9% of the CPU time.
