VSFS: A Searchable Distributed File System

In this paper, we propose a Versatile Searchable File System, VSFS, which builds POSIX-compatible namespace using a novel Namespace-based File Query Language (NFQL). This enables analytics applications to utilize VSFS high-performance file-search service without changing their data model. VSFS versatile file-indexing mechanism is designed to offer great flexibility for applications to control indices to satisfy analytics needs. The evaluations driven by two real-world analytics applications demonstrate VSFS´ high scalability and powerful data-filtering functionality.
