Description

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).
