Modern cloud systems are geo-replicated to improve application latency and availability.
Transactional consistency is essential for application developers; however, the …

We present Alvin, a system for managing concurrent transactions running on a set of
geographically distributed sites. Alvin supports general-purpose transactions, and …

This paper presents Granola, a transaction coordination infrastructure for building reliable
distributed storage applications. Granola provides a strong consistency model, while …

We describe the design and implementation of Walter, a key-value store that supports
transactions and replicates data across distant sites. A key feature behind Walter is a new …

Most geo-replicated storage systems use weak consistency to avoid the performance
penalty of coordinating replicas in different data centers. This departure from strong …

Many transaction systems distribute, partition, and replicate their data for scalability,
availability, and fault tolerance. However, observing and maintaining strong consistency of …

Client-side logic and storage are increasingly used in web and mobile applications to
improve response time and availability. Current approaches tend to be ad-hoc and poorly …

This paper introduces SPECULA, a novel replication protocol for Software Transactional
Memory (STM) systems that seeks maximum overlap between transaction execution and …

In this article we introduce GMU, a genuine partial replication protocol for transactional
systems, which exploits an innovative, highly scalable, distributed multiversioning scheme …

In this work we present OSARE, an active replication protocol for transactional systems that
combines the usage of Optimistic Atomic Broadcast with a speculative concurrency control …
