Renat, To clarify on the shortcut solution, are you saying 1) we add an adhoc event subscription to the workflow spec OR 2) add a one time event subscription to the workflow execution OR both?
I propose a separate worker/executor to process the events so to not disrupt the workflow executions. What if there are a lot of subscribers? What if one or more subscribers are offline? Do we retry and how many times? These activities will likely disrupt the throughput of the workflows and I rather handle these activities separately. Winson
