If publishes faster than calling SpinOnce, would CallBack Queue be filled up eventually?

If we have a publisher publishing at 40Hz, and the subscriber is calling SpinOnce at 20Hz, would our CallBack Queue be filled up eventually?

Depends on how long your callbacks run. But spinOnce does not just execute only one callback but it will empty the queue if possible and then return.
