I think you're right... I don't want to build an in-memory dataset, I just want to have a single dataset, but instead of having all graphs loaded together, I'd like to split them into their own folders such as "graph-1/", "graph-2/", "graph-3/" (each directory containing a TDB2 graph)... such that if I want to update a graph I can simply remove a directory and replace it with a new one. Is this possible?
