This paper presents a method that allows a replicated database system to provide a global isolation level stronger than the isolation level provided on each individual database replica. We propose a new multi-version concurrency control algorithm called, serializable generalized snapshot isolation (SGSI), that targets middleware replicated database systems. Each replica runs snapshot isolation locally and the replication middleware guarantees global one-copy serializability. We introduce novel… CONTINUE READING
