Metadata Update Performance in File Systems

"... Structural changes, such as file creation and block allocation, have consistently been identified as file system performance problems in many user environments. We compare several implementations that maintain metadata integrity in the event of a system failure but do not require changes to the on-d ..."

A five-year study of file-system metadata
- In Proceedings of the 5th USENIX Conference on File and Storage Technologies. USENIX Association
, 2007
"... For five years, we collected annual snapshots of file-system metadata from over 60,000 Windows PC file systems in a large corporation. In this article, we use these snapshots to study temporal changes in file size, file age, file-type frequency, directory size, namespace structure, file-system popul ..."

Change Management for Metadata Evolution
"... Abstract. In order to meet the demands of the Semantic Web, today’s ontologies need to be dynamic, networked structures. One important challenge, therefore, is to develop an integrated approach to the evolution process of ontologies and related metadata. Within this context, the specific goal of thi ..."

of this work is to capture the evolution of metadata due to changed concepts, relations or metadata in one of the ontologies, and to capture changes to the ontology caused by changes to the metadata. After a short discussion of the nature of metadata, we propose a methodology to capture (1) the evolution
Metadata logging in an NFS server

, 1995
"... Over the last few years, there have been several efforts to use logging to improve performance, reliability, and recovery times of file systems. The two major techniques are metadata logging, where the log records metadata changes and is a supplement to the on-disk file system, and logstructured fil ..."

A metadata approach to resolving semantic conflicts

These changes may occur at the source of the data or they may be changes in the specifications of the data semantics for the application. Methods are described for detecting these changes and for determining
