i'm kinda focused right now on hitting a milestone target in the next two weeks on the project i'm building with this but in two weeks i think i can be confident enough to pop it out by itself, since if it reaches that target it covers everything required for a paid relay with arbitrary storage back end interfaces
i haven't developed any other than the badger driver for the database but i intend to build one for another k/v store: https://github.com/akrylysov/pogreb
the rationale for using this one is that it is very fast at retrieval, way faster than anything else, and my intended use case of the database in my relay is for caching front end for a distributed data store backend, so most of the workload is actually read side, and that's something i know because i watch the activity of clients using my relay and they pull soooo much data over and over again, and pogreb gives fast speed without as high a memory use cost for the use case
