Also, is it possible to limit concurrency at the deployment level? I am implementing a job that I don't want running twice at the same time. It seems tags in a DeploymentSpec don't work for concurrency limits. Right now I might move the tag to the main flow

Tags should work on the deployment. I’ll try this in a bit

<@U036FLZP2H3> there are two levels of concurrency limits.

#1 Currently, using the `prefect concurrency-limit` command, you can set task-level concurrency limits.

2# The alternative to task-level concurrency limits are work-queue concurrency limits which allow you to set limits on a deployment level - this seems to be exactly what you want!  To create that, you can create a work-queue for a specific deployment UUID:
```prefect work-queue create -d 'uuid' test_queue```
this will return WORK_QUEUE_ID which you can use to set a limit for that to 1:
```prefect work-queue set-concurrency-limit WORK_QUEUE_ID 1```

more on that <https://orion-docs.prefect.io/concepts/work-queues/>

I suppose that will work... will need a work queue and agent for every job though

<@U01QEJ9PP53> Was that possible? I think it would be a really useful feature. I'm sure I'm not the only one who doesn

That I know for sure will be a built-in feature where the current run will just wait for the previous run to finish. It just hasn;’t been developed yet

Dang. I'll keep an eye on the changelogs. will put this on the backburner for now
