> (This clones OAK-2208 as that never made it into the 1.0 branch)
> This code currently has a hardwired optimization for MongoDB (returning an
> Iterable over a DBCursor). For all other persistences, a java List of all
> matching NodeDocuments will be built.
> I see two ways to address this:
> 1) Generalize the Mongo approach, where a query to the persistence can return
> a live iterator, or
> 2) Stick with the public DS API, but leverage paging (get N nodes at once,
> and then keep calling query() again with the right starting ID).
> 2) sounds simpler, but is not transactional; [~mreutegg] would that be
> sufficient?
