Hey folks, new to Prefect here. I am trying to prototype something leveraging global concurrency controls, https://docs.prefect.io/latest/guides/global-concurrency-limits/, and wondering how I can configure these limits from code? Is the only way to literally use the UI?

There are client methods for it. grabbing the docs, one second
hmm they might be missing from the docs but they're definitely there
n
I can read source
is the intent that they would not be set from within a task?
k
I'm not sure exactly what you mean
n
specifically one thing I want to try to so is to lower the slot decay significantly if a remote API throws a 429

great - I think 
update_global_concurrency_limit
getts me what I want

will report back!
This works, sort of. I believe I have found a bug: The 
slot_decay_per_second
via the UI allows you to set a float value (e.g. 0.1, and the docs even say that will work). the prefect 
client
stubs expect that value to be an 
int
, so sending a value of 0.1 to the server results in a configured value of 0. What is the best way for me to either submit a patch or an issue?
cc @Kevin Grismore maybe you know?

here ya go!
you're right, it's a float on the sever end of the model too https://github.com/PrefectHQ/prefect/blob/main/src/prefect/server/schemas/core.py#L682
n
I think the patch is probably as simple as just changing the client side type
k
you're welcome to open a PR if you'd like
n
it shouldn’t break anyone using that client method right now unless anyone is verifying isinstance() at runtime
k
yeah the actual API is expecting an openapi 
number
so it should be fine
n
submitted https://github.com/PrefectHQ/prefect/issues/12364 If I have some time, I will look at submitting a PR
