> Hmm - this only allows us to limit activities per worker, but what if you wanted to limit the activities on a workflow? > For example, if you have a workflow that needs to execute 64 activities, but only want 4 activities executing concurrently. Is that possible? You start 4 activities and start more when one of the executing activities is completed. Note that in Go SDK ExecuteActivity returns a Future. So the call is already asynchronous. You can use Selector for waiting on multiple Futures. > Also, is there a limit on how many activities you can have running in parallel at any point in time? Limiting the number of executing activities across multiple workers is not supported. Only a global rate list per task queue is supported. > I haven’t heard of swarm before, so maybe that terminology is why I didn’t jump to this. Do you have a rough description of what this attempts to do? It was contributed. So I’m not an expert in the mathematical model it implements. --- _[View the full topic](https://community.temporal.io/t/limit-concurrent-activities-in-parallel/2066)._
