You basically cannot adapt the optimal data layout to the available data. (I like to think of this issue as related to storing deltas: we let Git choose relatively freely what to delta against, and do not force a delta against the parent commit like others do; I think it is pretty obvious that our approach is more powerful.) So the simplest (yet powerful-enough) way I could imagine is to teach the reading part to accept any fan-out (but that fan-out is really only based on the object name, nothing else), and to adjust the writing/merging part such that it has a maximum bin size (i.e. it starts a new fan-out whenever a tree object contains more than a config-specifyable limit). I was certainly not thinking of something as complicated as Huffman.
