I assume that some sort of structural sharing is needed once the collections grow above a certain size. Also some support for caching would be nice.
A similar option might be something like https://github.com/BardurArantsson/cqrs *However*, I'm not sure I'd actually recommend using my particular library at this time. I'm probably going to be reworking it (slowly) quite a bit and currently there's no support for persistent[1] queries (see the CQRS/ES description linked from the README). Still, the ideas are sound and pretty simple. (See the PostgreSQL package for exactly what queries CQRS/ES maps to.) [1] As in: stored on disk. Regards,
