> Currently the compactor does just a rewrite of the super root node without
> any special handling of the checkpoints. It just relies on the node
> de-duplication cache to avoid fully exploding the checkpoints.
> I think this can be improved by subsequently rebasing checkpoints on top of
> each other during compaction. (Very much like checkpoints are handled in
> migration).
