Synchronous metadata management of large storage systems

Today filesystems of big companies are both huge and distributed amongst the world. They contain huge sets of metadata, but are not optimized to analyze them. In contrast, if metadata is stored in a database system and updated synchronously, it could be analyzed and processed in a much easier and straightforward way. Then even adding new attributes, not natively supported by the underlying filesystem, is easily possible. Thus, synchronous metadata storage in a database system can help managing and administrating huge filesystems efficiently but must not slow down the filesystem significantly. The aim of this paper is to describe possible solutions for synchronous metadata storage, inspect how such an integration of filesystem and database system might look like and evaluate the performance.
