Description

As a result of OAK-3348 we need to partially rework the memory estimation step done for deciding whether compaction can run or not. In oak-segment there was a delta value derived from the compaction map. As the latter is gone in oak-segment-next we need to decide whether there is another way to derive this delta or whether we want to drop it entirely.
