Résultat majeur : WEB DATA INDEXING IN THE CLOUD: EFFICIENCY AND COST REDUCTIONS
WEB DATA INDEXING IN THE CLOUD: EFFICIENCY AND COST REDUCTIONS
22 décembre 2012

J. Camacho-Rodríguez, D. Colazzo and I. Manolescu.
Int. Conf. on Extending Database Technology.
An increasing part of the world's data is either shared through the Web or directly produced through and for Web platforms, in particular using structured formats like XML or JSON. Cloud platforms are interesting candidates to handle large data repositories, due to their elastic scaling properties. Popular commercial clouds provide a variety of sub-systems and primitives for storing data in specific formats (files, key-value pairs etc.) as well as dedicated sub-systems for running and coordinating execution within the cloud.
We propose an architecture for warehousing large-scale Web data, in particular XML, in a commercial cloud platform, specifically, Amazon Web Services. Since cloud users support monetary costs directly connected to their consumption of cloud resources, we focus on indexing content in the cloud. We study the applicability of several indexing strategies, and show that they lead not only to reducing query evaluation time, but also, importantly, to reducing the monetary costs associated with the exploitation of the cloud-based warehouse. Our architecture can be easily adapted to similar cloud-based complex data warehousing settings, carrying over the benefits of access path selection in the cloud.
