RAM-DUR: In-Memory Deferred Update Replication

Many database replication protocols are based on the deferred update replication technique. In deferred update replication, transactions are executed by a single server, and certified and possibly committed by every server. Thus, servers must store a full copy of the database. This assumption is detrimental to performance since servers may not be able to cache the entire database in main memory. This paper introduces RAM-DUR, a variation of deferred update replication whereby transaction… CONTINUE READING
