Many database replication protocols have been designed for guaranteeing a serialisable isolation level, since it is appropriate for almost all applications. However, it also requires a tight coordination among replicas and might generate high abortion rates with some workloads. So, other isolation levels have also been considered, such as snapshot isolation(More)
Whereas the Strict Snapshot Isolation (SSI) level is nowadays offered by most of the centralized DBMSs, replicated databases do not usually provide it, since the traditionally considered approach, the pessimistic management, introduces enormous performance penalties that preclude it from production applications. Instead, distributed databases usually offer(More)
