Hello, Question related to Prefect API: Is there any way to update an existing

task concurrency limit tag

?

To update an existing task concurrency limit, you can use the Prefect Python client. Here's an example of how to set a new concurrency limit for a tag:

python
from prefect.client import get_client

async with get_client() as client:
    # set a new concurrency limit on the 'small_instance' tag
    limit_id = await client.create_concurrency_limit(
        tag="small_instance",
        concurrency_limit=10
    )

To remove all concurrency limits on a tag, you can use `PrefectClient.delete_concurrency_limit_by_tag`:

python
async with get_client() as client:
    # remove a concurrency limit on the 'small_instance' tag
    await client.delete_concurrency_limit_by_tag(tag="small_instance")

If you want to query the currently set limit on a tag, use `PrefectClient.read_concurrency_limit`:

python
async with get_client() as client:
    # read the concurrency limit on the 'small_instance' tag
    limit = await client.read_concurrency_limit(tag="small_instance")

For more information, you can refer to the [Prefect documentation on tasks](https://docs.prefect.io/latest/concepts/tasks/) and the [Task Run Concurrency page](https://docs.prefect.io/latest/ui/task-concurrency/).

Yes. There is create and delete but no update.

hmm, there's also a reset, but not seeing an update. what's your usecase?

I am writing everything as code. So i write config for all work queues and limits. On major releases of our code we reverify everything, create if doest exist and update if it exists.

unfortunately, I'm not sure its directly possible to do this right now. there is no route for updating concurrency limits, only create / read / delete / reset

Should I open an issue?

yes please! thank you

🫡will do it tomorrow. Thanks @Nate

👍

Just chiming in here, I think that

create_concurrency_limit**

currently overwrites the concurrency limit for an existing tag. You just have to pass in the tag's name and the new concurrency limit value.

Thanks I'll test it out
