Replication in Node Partitioned Data Warehouses

Authors

Abstract

In this paper we concentrate on guaranteeing efficient availability and promoting manageability in a node-partitioned data warehouse (NPDW). The objective is that the system be always-on and always efficient even when entire parts of it are taken offline for maintenance and management functions such as loading with new data or other DBA functionality. Replication has already been studied for parallel databases in general. We investigate how alternative replication strategies can be applied to the NPDW context and analyze advantages and drawbacks against metrics.
