Description	Existing data storage systems based on hierarchical directory tree do not meet scalability and functionality requirements for exponentially growing datasets and increasingly complex metadata queries in large-scale file systems with billions of files and Exabytes of data. This paper proposes a novel decentralized semantic-aware metadata organization, called SmartStore, which exploits metadata semantics of files to judiciously aggregate correlated files into semanticaware groups by using information retrieval tools. The decentralized design of SmartStore can improve system scalability and reduce query latency for both complex queries (including range and top-k queries), which is helpful to construct semantic-aware caching, and conventional filenamebased point query. The key idea of SmartStore is to limit In Proceedings of SC09
