Findings

Supports strong consistency and fault-tolerance

Open-source implementation available on multiple platforms

Designed for high availability in distributed environments

Abstract

This paper describes the design and architecture of Keyspace, a distributed key-value store offering strong consistency, fault-tolerance and high availability. The source code is available under the open-source AGPL license for Linux, Windows and BSD-like platforms. As of 2012, Keyspace is no longer undergoing active development.
