This is on our list : https://github.com/rethinkdb/horizon/issues/23 The big piece remaining that will help is write timestamps in the database, which we're going to try to land in RethinkDB 2.4. If we were controlling a traditional MVC frontend model and had control over the objects themselves, it would be easier to do optimistic updates. Since we're aiming to be compatible with a lot of frontend frameworks where immutability of the model is important, we have to carefully consider how to do it. That being said, it's super important, so it's near the top of our priorities

Hey @nileshtrivedi, We pushed a hotfix a few minutes after launch that resolved this issue [1] which you may be experiencing. You should try doing `npm update -g` if you're still on `horizon 1.0.0`. You can check with `hz version`. If this doesn't fix it for you, please open up an issue [2] and I will help you out. - [1] https://github.com/rethinkdb/horizon/issues/392 - [2] https://github.com/rethinkdb/horizon/issues/new
In Horizon 1.0: a realtime, open-source JavaScript back end from RethinkDB
For apps that don't necessarily have the realtime requirement, Kinto [1] is another really cool open-source backend solution that focuses on the offline-first scenario. It's built by the Firefox Sync team and used in production at Mozilla. That said, at first glance there doesn't seem to be anything stopping anyone from building a caching layer on top of Horizon to enable offline-first functionality. Definitely going to be keeping an eye on this as well! EDIT: It looks like they are in fact considering offline-first support already [2]!

The current version of Horizon doesn't do optimistic updates, but it's on the roadmap. Check out https://github.com/rethinkdb/horizon/issues/23. This is relatively easy because RethinkDB itself has support for notifying the client via a feed when a particular update has landed (i.e. the RethinkDB client can correlate the write with a feed message). It just didn't make it into v1, but will happen soon.
