> Redis is a cache
Redis is much more than a cache, you can model graph data structures with Redis primitives, and the redisgraph module compares directly against Dgraph.

The entire graph is stored in memory and only spans one server. I personally am not sure what happens when that server goes down. How many minutes worth of data is lost? What's the replication strategy for another server to take over the traffic? And what about transactions and correctness?
Those things matter a lot to Dgraph users who are storing and serving their source of truths. Horizontal scalability, persistence, correctness and avoiding downtime with consistent replication have been cornerstones for the design of Dgraph.
My point was that those questions I mentioned above are important to Dgraph users and I don't think Redis even projects itself as a persistence-first DB. I might be wrong. Either ways, our audience is quite different when it comes to enterprises at least.
I know the founders of Redis Labs, met them as well and they're awesome people.
