@Marvin how can i rename a flow deployment that i created with

flow.from_source

so that in the UI on the server it has a different name?

@Marvin how can I extend the base job template KubernetesClusterConfig to request the cpu and memory for a pod?

Hello 🙂 I believe I ran into a threading problem yesterday. I am converting some data extraction pipelines to prefect 2 flows, which works fine for most of them. I just add the decorators and some logging. But one of the data pipelines uses sqlite for intermediate storage, and this is the error message I receive:

sqlite3.ProgrammingError: SQLite objects created in a thread can only be used in that same thread. The object was created in thread id 140193261803264 and this is thread id 140192735962880.

I can also paste the part of the code where sqlite is called. I am also trying to guess the reason behind the error. There is an sqlite object created in a function. Within the function I define another function which uses this object. But both python functions are not prefect flows or tasks. They live within a bigger prefect flow. So here comes my first question: Does prefect 2 create a different thread for each nested function inside a flow or a task. Otherwise I cannot explain why the 2 parts of the code would run in different threads.

Has anyone run into this issue when trying to run

flow.visualize()

? I installed the viz package with

pip install prefect[viz]

but am still getting this:

Hi,all After upgrading of Prefect 2 to 3, "run-graph" always say "This flow run did not generate any task or subflow runs" at a "Runs" pane with Deployment on Kubernetes Worker. Somehow but when I execute same flow at other workload, it works. why? woker "run-graph" show: Local Execution. does not show: Kubernetes Worker

How does one get the current flow run url programmatically?

@Marvin is it possible to set nodeSelector and tolerants on a work pool so that all flows described in my prefect.yaml that are associated with that work pool will be scheduled on a specified node pool?

Is there a callback for when a flow starts? I see there are callbacks for on_completion and on_failure

@Marvin how can I send a Teams notification if one of my flow runs fail in prefect 3?
