    Howdy! I'm currently working on adding a way to roll back a potentially bad deploy and was wondering if there is a way to have prefect basically "stop the world" on a particular flow

    I have code currently that will set all flow runs + their child task runs to cancelled but it looks like that won't stop tasks from being submitted to Dask

    I'm using jaydebeapi on windows and prefect keeps throwing the error java.sql.SQLException: No suitable driver found for. This flow works when not using prefect server. However, it appears it can't find the jar file possibly. Where is the best place to put the file? This is also using dask distributed

    Question about setting
    upstream_tasks
    to the same task being called twice with different arguments. I have something like
    A(abcd)
    B.set_dependencies(upstream_tasks=[A], keyword_tasks=...)
    A(defg)
    B.set_dependencies(upstream_tasks=[A], keyword_tasks=...)
    where B must run after A, and each gets called with two separate sets of Parameters. If I call
    B.set_dependencies(upstream_tasks=[A])
    twice, will the second B wait on the second A? And is this the idiomatic way to do this?

    Hi everyone 👋 Data engineer with a remote sensing/ IOT sensor background here. I'm looking at Prefect to orchestrate processing-intensive scientific computing workflows on AWS. Currently, we're using AWS Batch + ECS to run docker containers but it's a really limited map-reduce thing. Ideally we'd like a system that would allow us to leverage our existing docker containers and build them into more complex, parameterized DAG topologies. We've tried Airflow... and hit almost all of the limitations mentioned in prefect's docs 🙄 We're just getting started with Prefect but it looks very promising so far! Are there any other folks using prefect to tie together already-dockerized processes?

    Is it possible to set the flow run name when using a Clock? I’m using one flow, multiple clocks with different parameters and it would be useful to be able to name the flow-run

    We're running into configuration issues with the graphql url. We've set server.ui.graphql_url to the proper host and path, but the UI doesn't use the config value. Is there a param for this not listed in the example config.toml?
