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 techniques to provide a stronger global isolation level, namely readset extraction and enhanced certi\ufb01cation that prevents read-write and write-write con\ufb02icts in a replicated setting. We prove the correctness of the proposed algorithm, and build a proto-type replicated database system to evaluate SGSI performance experimentally. Extensive experiments with an 8 replica database system under the TPC-W workload mixes demonstrate the practicality and low overhead of the algorithm.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>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.
