> Changes look good to me. One additional question from me is that do we
have a common sense on how much performance overhead it would bring with
sampling?
I don't have an accurate number but I believe the overhead shouldn't be
large since the ExecutionStateSampler uses a separate daemon thread and only
updates the timestamps in ExecutionStates every 200ms, I believe this is what
the legacy worker has been doing as well.
