Introduction

nbase-arc (n-base-ARC) is an open source distributed memory store based on Redis. It provides a zone of clusters where each cluster is composed of synchronously replicated Redis server groups that can scale-in/out without service interruption.

Features

• Multi-cluster zone
  • You can make multiple clusters within a single zone. Each cluster is distinguished by its name.
  • Configuration master manages all cluster information safely. Configuration master also does failure detection and automatic fail-over of the cluster components
• A Cluster is a single big Redis server
  • Clients access Redis servers indirectly via gateways. A cluster acts like a single big Redis server instance with multiple access points.
  • Gateway is a Redis proxy that accepts Redis requests from client.
• High availability and consistency
  • Unlike Redis replication which is asynchronous and can lose changes when a master crashes, nbase-arc implements synchronous replication layer that supports both high availability and consistency. Changes replied to clients are durable even when the master side of the replication is crashed.
• Service without interruption
  • All cluster management operations can be performed without service interruption. You can even upgrade gateways (client access directly) transparently if you use nbase-arc C/Java client libraries.
