Extensible storage system

摘要

A massively scalable architecture has been developed for providing an extensible storage system that is capable of handling hundreds of millions of users and tens of billions of files. The storage system includes to a plurality of storage clusters, each storage cluster having one or more storage servers. Each storage element has a corresponding schema object that is used to parse the data elements into data and attributes. Applications executing on the web servers are able to dynamically define a new type of element for storage within storage system. In one configuration the schemas are defined in Extensible Markup Language (XML).
