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 …

In this paper we present PEAS, a robust energy-conserving protocol that can build long-
lived, resilient sensor networks using a very large number of small sensors with short battery …

We consider the problem of separating consistency-related safety properties from availability
and durability in distributed data stores via the application of a" bolt-on" shim layer that …

The need for high availability and performance in data management systems has been
fueling a long running interest in database replication from both academia and industry …

Due to the rapid acceptance of web services and its fast spreading, a number of mission-
critical systems will be deployed as web services in next years. The availability of those …

Partial replication is a way to increase the scalability of replicated systems: updates only
need to be applied to a subset of the system's sites, thus allowing replicas to handle …

Code reviews have been conducted since decades in software projects, with the aim of
improving code quality from many different points of view. During code reviews, developers …

This paper describes the design, implementation, and evaluation of areplication scheme to
handle Byzantine faults in transaction processing database systems. The scheme compares …

The growing demand for data-driven features in today's Web applications--such as targeting,
recommendations, or predictions--has transformed those applications into complex …

Replication is a key mechanism to achieve scalability and fault-tolerance in databases. Its
importance has recently been further increased because of the role it plays in achieving …
