> When batches are executed with memory, console or foreach format, `assertNotPartitioned` will check whether output is not partitioned and throw AnalysisException in case it is.
> But I wonder it's better to log warning rather than throw the exception because partitioning does not affect output for those formats but also does not bring any negative impacts.
> Also, this assertion is not applied when the format is `console`. I think in this case too, we should assert that .
> By fixing them, we can easily switch the format to memory or console for debug purposes.
