摘要: Many distributed databases use an epidemic approach to manage replicated data. In this approach, user operations are executed on a single replica. Asynchronously, separate activity performs periodic pair-wise comparison of data item copies detect and bring up date obsolete copies. The overhead due grows linearly with the number items in database, which limits scalability system.
