> Add a flag to skip InputSelectable preValidate step
> ---------------------------------------------------

> Key: FLINK-32745
> URL: https://issues.apache.org/jira/browse/FLINK-32745
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream, Runtime / Configuration
> Reporter: Chesnay Schepler
> Priority: Major
> Fix For: 1.19.0
>
>
> {{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.
