Consistency of Data Replication Protocols in Database Systems: a Review
In this paper, a review for consistency of data replication protocols has been investigated. A brief deliberation about consistency models in data replication is shown. Also we debate on propagation techniques such as eager and lazy propagation. Differences of replication protocols from consistency view point are studied. Also the advantages and disadvantages of the replication protocols are sh...
متن کاملD Database Replication Protocols
Databases are replicated in order to obtain two complementary features: performance improvement and high availability. Performance can be improved when a database is replicated since each replica can serve read-only accesses without requiring any coordination with the rest of replicas. Thus, when most of the application accesses to the data are read-only, they can be served locally without prev...
متن کاملThe Performance of Weak-consistency Replication Protocols
Weak-consistency replication protocols can be used to build wide-area services that are scalable, fault-tolerant, and useful for mobile computer systems. We have developed the timestamped anti-entropy protocol, which provides reliable eventual delivery with a variety of message orderings. Pairs of replicas periodically exchange update messages; in this way updates eventually propagate to all re...
