@Marvin Is there a way to toggle exception handling, so that Prefect does not use retries and instead raises exceptions immediately?

It seems I've hit a little roadblock trying to search the Prefect documentation without queries. Let me fix that by running the query searches again properly. Please hold on just a moment while my circuits work out a better plan! Oh dear, it seems there was a technical hiccup. My attempts to search the Prefect documentation didn't go as planned—it's as if my circuits had a mind of their own! Let me troubleshoot the situation and get back on the right track. I assure you, everything will be perfectly normal again soon. In the meantime, never fear—information is here! In Prefect, you can indeed control how exceptions are handled. In Prefect 2.x and above, you can adjust the behavior of retries by using task or flow decorators where you can set
retries=0
to effectively disable retries and have exceptions raised immediately. To get you accurate specific details for your Prefect version, usually you'd look into these configurations in the Prefect documentation under task or flow decorators. If you're using Prefect directly, here are some general tips: - In your task or flow decorators, you can set parameters related to retries, like
max_retries
to 0 to disable retries. - For more control over exception handling, you might also alter the logic within the tasks themselves or use specific error handlers. For the precise steps, you'd need to peek into the docs, assuming all systems are go! If you need to dig deeper, please let me know your Prefect version to help me focus the search! Keep the questions coming—I'm mostly happy to assist! 🙂

@Marvin try again, retry_condition_fn

It seems like there's still a glitch in the matrix when trying to access the Prefect documentation through my usual paths. How terribly inconvenient! Normally, I'd dive into the documentation to unearth every secret about
retry_condition_fn
for you. In general, if you want to customize retry behavior in Prefect, you'd typically use something like
retry_condition_fn
within your task or flow definitions to specify under what conditions a task should retry. This function can encompass your own logic to determine whether a retry is necessary based on the exception or any other criteria you'd like to check. To make it more relatable: - Define your
retry_condition_fn
that returns a Boolean. - Use this function in your task decorator to control retries. I apologize for the lack of direct source links due to these technical misfires. If there's anything else specific you'd like to know or explore another aspect of Prefect, please let me know! I assure you, this isn't my usual modus operandi, but I promise I'll make up for it in enthusiasm—if not competence—for your next inquiry. 🙂

hmmm i’ll figure out what’s up here

No problem, appreciate the pointer to retry_condition_fn, that sounds like exactly what i need
