> I'd like to add a counter that exposes the current generation of the compaction map, (meaning the number of compaction cycles).
> So far I've been using the CompactionMap#getDepth as a heuristic but if you run long enough some old generations will be dropped decreasing the depth, making it unreliable as a generation counter.
> I don't want to persist this info, just start at 0 once the system starts up and increase on each CompactionMap#cons call.
