Research and application of data synchronization based on group communication technology

Abstract

To solve the problem of data consistency in distributed database system, this paper presents a global transaction-oriented synchronization model based on the features of total order service in group Communication. This model combines the transaction on each node with the technology of Atomic Broadcast and guarantees the data consistency of the system strictly. Results show that this model reduces the traffic of synchronization and improve the efficiency of eager replication. © 2012 Springer-Verlag Berlin Heidelberg.
