Distributed cloud-native graph database with NebulaGraph Docker extension
Posted on May 4, 2023, Level intermediate Resource Length medium
Graph databases have become a popular solution for storing and querying complex relationships between data. As the amount of graph data grows and the need for high concurrency increases, a distributed graph database is essential to handle the scale. Finding a distributed graph database that automatically shards the data, while allowing businesses to scale from small to trillion-edge-level without changing the underlying storage, architecture of the service, or application code, however, can be a challenge.
