Non-Monotonic Snapshot Isolation (NMSI), a variant of the widely deployed Snapshot Isolation (SI), aims at improving scalability by relaxing snapshots. In contrast to SI, NMSI snapshots are causally… (More)
Distributed systems provide resources to a large number of applications today. They are designed to provide reliable and continuous services despite the failures of some of their components.… (More)
