> OAK-4631 introduced a simplified serialisation for record ids. This causes
> their footprint on disk to increase from 3 bytes to 18 bytes. OAK-4631 has
> some initial analysis on the effect this is having on repositories as a
> whole.
> I'm opening this issue as a dedicated task to further look into mitigation
> strategies (if necessary).
