Wait node blocking other execution

Questions

Describe the problem/error/question

We have a workflow that sometimes triggers simultaneously for the same entity (from different type of events). To avoid the executions interfering with each other, I added a Wait node for one of the event types. However, it seems like the Wait node blocks the other execution as well. So in the end the executions still execute the same steps simultaneously .

I could fix this issue by:

  1. Duplicating the workflow (one for each event), but it is cleaner to have it in a single workflow, because the do exactly the same thing.
  2. Implement a message broker.

My question is rather why the Wait node blocks the other execution? If I use the Code node with an async sleep, it is working as expected (the other execution is being processed while the one is “sleeping”).

Please share your workflow
