   Thanks for opening this PR @eaglewatcherwb. I'm not sure whether we already reached agreement
on the overall design for adaptive parallelism. I see some merge conflicts with the current
effort to make the scheduler pluggable. I would suggest to wait until the new interfaces are
in place before adding more things to the `ExecutionGraph`. The idea was to make the `ExecutionGraph`
a leaner structure and let the specific `Scheduler` implementation handle things like adaptive
parallelism. Therefore, I would suggest to close this PR.
