> {{StreamingJobGraphGenerator#preValidate}} has a step where it checks that no operator implements {{InputSelectable}} if checkpointing is enabled, because these features aren't compatible.
> This step can be extremely expensive when the {{CodeGenOperatorFactory}} is used, because it requires all generated operator classes to actually be compiled (which usually only happens on the task manager).
> If you know what jobs you're running this step can be pure overhead.
> It would be nice if we'd have a flag to skip this validation step.
