Context We have an automated workflow that we are in the process of applying to a large chunk of our MDS+ database. At the moment the going is slow because we limit the amount of concurrent instances of this workflow to avoid overloading our MDS+ server. The workflow is launched by a service account, and if the MDS+ server would automatically hold concurrent connections from this service account when a certain threshold is reached, we could scale-up without having to worry about our MDS+ server.

Question Is it possible to automatically hold connection attempts for a specific user once a threshold of connections has already been opened by this user. Note that we want to hold them and not reject them as that would cause unacceptable failures in our workflow downstream.
