Dgraph on openEuler 22.03

Dgraph is a horizontally scalable and distributed GraphQL database with a graph backend. It provides ACID transactions, consistent replication, and linearizable reads. It's built from the ground up to perform a rich set of queries. Being a native GraphQL database, it tightly controls how the data is arranged on disk to optimize for query performance and throughput, reducing disk seeks and network calls in a cluster. Dgraph's goal is to provide Google production-level scale and throughput, with low enough latency to serve real-time user queries over terabytes of structured data. Dgraph supports GraphQL query syntax, and responds in JSON and Protocol Buffers over GRPC and HTTP. Dgraph is written using the Go Programming Language. # Start 1. Depending on the configuration of the instance, you may need to wait up to 5 minutes for the server to finish initializing; 2. Go to http://:8080. When you see "Dgraph browser is available for running separately using the dgraph-ratel binary", it means that the server is running normally.
