Today no good options exist for databases on the edge (think CDNs) or even right on the client. But enough of the research if you want to make it yourself. You can have a partial view of the database on an edge node or a client with updates merging and propagating without conflicts.

There was Datanet: http://highscalability.com/blog/2016/10/17/datanet-a-new-crd...

It's CRDT-based automatic merging of JSON-like structures with core and edge nodes. It looks like it's called Kuhiro now, although the status is unknown: https://www.kuhiro.com

Redis will add a client cache on the protocol/client.
