Database Replication Using Generalized Snapshot Isolation

Willy Zwaenepoel, Sameh Mohamed Elnikety, Fernando Pedone

Generalized snapshot isolation extends snapshot isolation as used in Oracle and other databases in a manner suitable for replicated databases. While (conventional) snapshot isolation requires that transactions observe the “latest” snapshot of the database, ...

C-JDBC: Flexible Database Clustering Middleware

Willy Zwaenepoel, Emmanuel Cecchet

Large web or e-commerce sites are frequently hosted on clusters. Successful open-source tools exist for clustering the front tiers of such sites (web servers and application servers). No comparable success has been achieved for scaling the backend database ...

Processeur à haut degré de parallélisme basé sur des composantes sérielles

Ralph Hoffmann

Nowaday, the world of processors is still dominated by the RISC architectures, which foundations have been laid down in the 70's. The RISC concept may be summarized by one word : simplicity. With this concept, much simpler architectures are born, in partic ...

The Database State Machine Approach

Rachid Guerraoui, André Schiper, Fernando Pedone

Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distributed transactional mechanisms, such as atomic commitment. We present the Database State Mac ...

Conflict-Aware Scheduling for Dynamic Content Applications

Willy Zwaenepoel

We present a new lazy replication technique, suitable for scaling the back-end database of a dynamic content site using a cluster of commodity computers. Our technique, called conflict-aware scheduling, provides both throughput scaling and 1-copy serializa ...

Walking Four Machines By The Shore

Anastasia Ailamaki

Recent studies have shown that the hardware behavior of database workloads is suboptimal when compared to scientific workloads, and have identified the processor and memory subsystem as the true performance bottlenecks, when running decision-support worklo ...
