Online data migration for autonomic provisioning of databases in dynamic content web servers
Gokul Soundararajan, Cristiana Amza · Conference of the Centre for Advanced Studies on Collaborative Research · 2005
This paper introduces an efficient data migration technique for provisioning new databases to workloads in dynamic content servers. Although many solutions for database replication exist, an efficient method for joining new replicas to a running system has not been implemented. We propose and implement a data migration algorithm that allows quick addition of replicas with minimal disruption of transaction processing. Furthermore, we show that our approach can also be used for fault management and re-integrating failed databases. We investigate our algorithm for transparent provisioning in the database tier using the TPC-W e-commerce benchmark and the RUBIS online auction benchmark. We demonstrate that our technique provides quality of service under different load and failure scenarios.
