Citrusleaf: A Real-Time NoSQL DB which Preserves ACID

In this paper, we describe the Citrusleaf real-time distributed database platform that is built using the core principles of traditional database consistency and reliability while also being fast and flexible enough for use in high-performance applications like real-time bidding. In fact, Citrusleaf is unique among NoSQL databases for its ability to provide immediate consistency and ACID while still being able to consistently exceed the high performance and scalability standards required by demanding real-time applications. This paper describes how the Citrusleaf system achieves the marriage of traditional database reliability, including immediate consistency and ACID, with flexibility and operational efficiency. Citrusleaf scales linearly at extremely high throughput while keeping response time in the sub-millisecond range as demonstrated by the test results presented here. This kind of performance has enabled Citrusleaf to become the underlying component of some of the world‟s largest real-time bidding networks.
