yeah this I imagined was the poor man s solution I was wondering if prefect had something built in for this

Deceivious · Answer

I would maybe rename main and make it a flow and trigger the other 2 flows as sub flows if you only want a single deployment But cant say more without more context on why that would be `a poor man s solution` Its simple and it works

Federico Zambelli · Answer

yeh sorry poor man s solution probably was not the proper term Lemme illustrate better

Imagine you have a task or a bunch of that return unpickleable objects and therefore can t be cached This is my current case as i have a couple of tasks that return async generators Eventually in the first flow I persist the result of these generators to disk first flow and later do something else with this results reading from disk 2nd flow I would like to say skip the execution of first flow if input parameters are the same as the last ones used for instance

Deceivious · Answer

Your first task could be ```def generate or load items just an example if file exists return load items return generate items ``` But yes prefect doesnt have in built support for this use case as far as I am aware
