I don’t see task

state_handlers

functionality in Orion/Prefect2.0. Is is on the roadmap? (or I’m I missing something..) thanks

You're 100% correct; there are no state handlers, but for a very good reason - they are no longer needed! 🙂 given that you may write any Python code within your flows in Prefect 2.0, state handlers can be replaced with simple if/else statements. Check this page for more details

thanks, this makes sense. Still -I would strongly advocate for the state-handler as a useful abstraction to have. Repeating if/then code blocks in every task just to get basic ‘alert on failure’ behavior seems like a big step backward. Especially from a ‘negative eng.’ POV

Repeating if/then code blocks in every task

isn't it the same as what you would have to do in a state handler? if you look at the link I sent: #1 1.0 syntax

if new_state.is_failed():

#2 2.0 syntax:

if task_future.get_state().is_failed():

just to get basic ‘alert on failure’ behavior

regarding that, we agree with you, and we're working on some very cool features to provide you with highly flexible yet still easy to use ways of implementing such alerts - follow the #CKNSX5WG3 channel in the next months, it will be 🔥 amazing

thx, I get a lot of value from the flexibility and simplicity of the prefect1.0

state_handlers

task parameter/API. E.g.

state_handlers=slack_notifier(only_states=[Failed, Retrying])
