SnapShot: Replication Timing

Robust Snapshot Replication

An important technique to ensure the scalability and availability of clustered computer systems is data replication. This paper describes a new approach to data replication management called Robust Snapshot Replication. It combines an update anywhere approach (so updates can be evaluated on any replica, spreading their load) with lazy update propagation and snapshot isolation concurrency contro...

SnapShot: Origins of DNA Replication

The fundamental unit of DNA replication, the replicon, is governed by a cis-acting replicator sequence and a trans-activating initiator factor. Despite the increased size and complexity of eukaryotic genomes, eukaryotic DNA replication continues to be guided by the fundamental principles and concepts established in the replicon model.

Second Order Snapshot-Log Relations: Supporting Multi-directional Database Replication Using Asynchronous Snapshot Replication

Multi-directional asynchronous replication is a desired mechanism which allows updates to be performed locally at any site, and later propagated asynchronously to other sites. This paper proposes using second order snapshot-log relations as a mechanism for extending the use of single-directional asynchronous replication to multidirectional. The proposed mechanism is fully based on DBMS core too...

Multi-Master Replication for Snapshot Isolation Databases

Lazy replication with snapshot isolation (SI) has emerged as a popular choice for distributed databases. However, lazy replication requires the execution of update transactions at one (master) site so that it is relatively easy for a total SI order to be determined for consistent installation of updates in the lazily replicated system. We propose a set of techniques that support update transact...
