Re: Logging Kafka during exceptions


Hi Paul,

Yes correct, Flink shouldn’t make any assumptions on what is inside the user function.

That is true, the exception may not be from a direct result of unexpected data, but the incoming data coupled by the state of the job is causing unexpected behaviour.  From my perspective, I wouldn’t want to defensively code my function to the n-th degree, I would rather try to understand why my function was failing (either due to the message I’m processing at the time, along with the state of the function) and fix the issue that way.  Then I’d defensively code the function as appropriate.

Thoughts?


Regards,
Scott
