Review Comment:
`txCountByCatalogVersion` is initialized as `new ConcurrentSkipListMap<>()`
(mind the lack of external comparator), what means all entries will be sorted
naturally in ascending order. Here you get _last_ entry, given the ascending
order this results in the biggest version used so far. But this method must
return minimal required time.
The fact that all tests have passed freaks me out tbh
