> Syncbase: "Offline-first and peer-to-peer, Syncbase provides local storage that opportunistically syncs data".

I have an application for that _right now_. Syncbase doesn't look ready though, does anyone know of an alternative data store that ticks all those boxes? e.g. I was looking at Cognito, but it lacks peer-to-peer.

You should take a look at Noms:

Happy to answer questions here or in our Slack channel.

Nothing else does what vanadium does, especially at its sophistication level. I don't know if I'd use it in production yet unless you are willing to put in some engineering resources, but you're unlikely to find something else as well made elsewhere. This is the product of a very elite team... which means it's also very complicated to use.

That's an unfortunate assumption. Looking back at historic examples, the Windows API was complicated to use while the NeXTSTEP API wasn't. Is there any question which was created by an "elite team"?

Syncbase is the attempt to simplify it and abstract a lot of it. It's API is much more straightforward and is fairly easy to work with.

Part of the complexity is that it's solving like 15 major problems at the same time in an interconnected way. It's also solving them for people like google which means there are a lot of requirements for all the things it needs to do.

Because it does new things, in addition to old things in new ways, there's a steep learning curve for all of its concepts. I totally agree that doesn't mean it couldn't be more elegant and "simple," but the win32/nextstep analogy isn't fair as they were far more similar than vanadium is to anything else. Vanadium is like a hybrid of (to use existing concepts) dns/http/ssl/json/bluetooth/nosql/ntp/kerberos and more. When you put it all together there isn't a lot of existing references or cognitive frames to help you "get it" righ away.

The outcome I'm looking for is basically CRDT (or something very like it) using only BYO smartphone & laptop devices (acting as both the forwarding nodes and the application client), robust against nontechnical user mishap and patchy/absent Internet connectivity.

I was looking at http://www.opengarden.com/meshkit.html but they don't seem interested in my scale.

I'd go with something that's more production ready / supported. Don't know about meshkit but sounds cool.

Hod @ Couchbase here. Depending on what you mean, I have to disagree. Are you talking about Vanadium Core, or Vanadium and Syncbase? From what I'm reading, Couchbase does significantly more than Syncbase. It supports many of the security features of Vanadium, although it doesn't have ACLs with things like proximity built-in.

Couchbase Lite does all this, and is a mature, shipping product with many real-world deployments (including peer-to-peer as a primary use). It's a JSON document database, with full map/reduce indexing/query capabilities. It uses MVCC (similar to git) to handle offline first + conflict resolution.

Couchbase Lite can be used stand-alone, or as part of the Couchbase Mobile stack, which includes Sync Gateway and Couchbase Server. Everything is open source, too.

I'm happy to answer questions here, you can ping me on twitter, or through our forums, etc. Hod @ Couchbase
