https://www.linkedin.com/blog/engineering/infrastructure/introducing-northguard-and-xinfra Northguard is a log storage system with a focus on scalability and operability. To achieve high scalability, Northguard shards its data and metadata, maintains minimal global state, and uses a decentralized group membership protocol. Its operability leans on log striping to distribute load across the cluster evenly by design. Northguard is run as a cluster of brokers which only interact with clients that connect to them and other brokers within the cluster.
