PowerDB-IR - Information Retrieval on Top of a Database Cluster
Our current concern is a scalable infrastructure for information retrieval (IR) with up-to-date retrieval results in the presence of frequent, continuous updates. Timely processing of updates is important with novel application domains, e.g., e-commerce. We want to use off-the-self hardware and software as much as possible. These issues are challenging, given the additional requirement that the resulting system must scale well. We have built PowerDB-IR, a system that has the characteristics sought. This paper describes its design, implementation, and evaluation. PowerDB-IR is a coordination layer for a database cluster. The rationale behind a database cluster is to ’scale-out’, i.e., to add further cluster nodes, whenever necessary for better performance. We build on IR-to-database mappings and service decomposition to support high-level parallelism. We follow a three-tier architecture with the database cluster as the bottom layer for storage management. The middle tier provides I...
