Database replication is widely used to improve both the performance: and resilience of database management systems. Although most commercially available solutions and the large majority of deployments use asynchronous updates in a shared nothing architecture, there is an increasing demand for additional guarantees, configuration flexibility, and manageability.

Examples of this demand abound. The upgrade of current fail-over clusters to active-active configurations, thus leveraging the additional computational resources for additional performance. The deployment of eager update replication over a MAN or WAN for disaster recovery, without resorting to volume replication, thus improving manageability and performance. The combination of both local clusters and wide-area systems in grid-style large scale systems poses new challenges in performance and manageability. The drive for self-manageable systems also discourages the need for human intervention in recovery and conflict solving, thus favoring eager update approaches. Finally, typical loads of current middleware and applications might allow novel trade-offs between resilience and performance that are not viable with OLTP loads.

The goal of the workshop is to bring together researchers and practitioners from the database and fault-tolerant distributed systems communities to discuss the current state of the art, pending challenges and trends, and novel solutions in the design, implementation and deployment of database replication. Topics covered in the workshop include cluster, MAN and WAN replication protocols, replication middleware, group communication based replication, self-manageable and autonomic replicated databases, replication transparency and client interfaces, novel applications and loads for replicated databases.
