Abstract:Modern online services rely on data stores that replicate their data across geographically distributed data centers. Providing strong consistency in such data stores results in high latencies and makes the system vulnerable to network partitions.

In this paper we present UNISTORE, the first fault-tolerant and scalable data store that combines causal… Show more
