> While doing some memory profiling on the store, it became clear that at the
> moment the metadata of the objects takes up much more space than it should.
> In particular, for each object:
> * The object id (20 bytes) is stored three times
> * The object checksum (8 bytes) is stored twice
> We can therefore significantly reduce the metadata overhead with some
> refactoring.
