A Suite of Database Replication Protocols based on Group Communication Primitives
Bettina Kemme, Gustavo Alonso
Abstract:
This paper proposes a family of replication protocols based on group
communication in order to address some of the concerns expressed by database
designers regarding existing replication solutions. Due to these concerns,
current database systems allow inconsistencies and often resort to centralized
approaches, thereby reducing some of the key advantages provided by
replication. The protocols presented in this paper take advantage of the
semantics of group communication and use relaxed isolation guarantees to
eliminate the possibility of deadlocks, reduce the message overhead, and
increase performance. A simulation study shows the feasibility of the approach
and the flexibility with which different types of bottlenecks can be
circumvented.
