Connect CDC

Yes, I've seen this happen during investigations. Initially it looked like someone had manually restarted the request, but the root cause was simply CDC's automatic recovery mechanism restoring previously active kernels and requests after the Listener ...

Yes, I've seen this many times. In most cases, the root cause was an apply-side error or continuous source activity preventing CDC from catching up. Once the underlying issue was resolved, the queues drained normally. Great summary and practical guidance! ...
