@Marvin does a workpool concurrency apply to subflows?

nope

too fast

Work pool concurrency limits apply to flow runs, restricting concurrent runs of matching flows. For example, if a work pool has a concurrency limit of 5, it will only release new work if fewer than 5 matching runs are currently in a Running or Pending state Work Pools. While the documentation excerpts do not explicitly state how work pool concurrency affects subflows, we can infer that since subflows are part of a larger flow run, the concurrency settings of the work pool will likely apply to the entire flow, including its subflows. Subflows don't run independently but within the context of their parent flows, so the concurrency limitations would logically include them. For detailed behavior and configuration of subflows within work pools, it would be best to check for more specific documentation or reach out to Prefect support.

so the concurrency limitations would logically include them.
