> As pointed out by [~joseph.torres] in [https://github.com/apache/spark/pull/20936],
both epoch queue and commits/offsets maps are unbounded by the number of waiting epochs.
According to his proposal, we should introduce some configuration option for maximum epoch
backlog and report an error if the number of waiting epochs exceeds it.
