Scalable Replication in Database Cluster
Marta Patiño-Martínez, Ricardo Jiménez-Peris, Bettina Kemme, Gustavo Alonso
In this paper, we explore data replication protocols that provide
both fault tolerance and good performance without compromising
consistency. We do this by combining transactional concurrency
control with group communication primitives. In our approach,
transactions are executed at only one site so that not all nodes
incur in the overhead of producing results. To further reduce
latency, we use an optimistic multicast technique that overlaps
transaction execution with total order message delivery. The
protocols we present in the paper provide correct executions while
minimizing overhead and providing higher scalability.
