Dgraph is designed to run on Kubernetes.
Also doesn't look open-source at first glance.
Even though it says ”graph” you don’t need to write graph traversal queries - just describe in GraphQL the nested data model you want to get out of the database and that’s what you will get.
Community edition is open source.
If that is true, you could definitely not make it less obvious. This is not the impression I got from your repo ("variously licensed under the Apache Public License 2.0 (APL) and the Dgraph Community License"). Neither your docs nor your website mensions a "community edition" either.
Also, first Google hit is dgraph.io:
> The only open source, AI-ready graph database that gives developers the tools to quickly build distributed applications at scale.
