We manage that today using Neo. Node types are represented by an array property on the node - therefore a node can be of many types. We then utilize relationships to provide an implements relationship that enables arbitrarily deep and complex inheritance/implementation scenarios. My core

The DB would do it in memory too, wouldn't it? In the case of a complex traversal, indexes don't really apply, since the ordering and the traversal order are unrelated, so you'd generally need to sort in memory anyway. Whether you do it as you add elements to the traversed list of stuff or do
