Bulk Operations: As SRB Federations grow large in terms of numbers of objects, it becomes more and more critical to be able to handle operations on a large number of objects efficiently. SRB supports bulk operations like bulk register, import, export, copy, move, replicate, and delete to get large tasks done much more quickly. Bulk operations feature data streaming in parallel streams so that multiple files can be sent in parallel to a Storage Resource. XML is used as a metadata transport protocol. With bulk operations, thousands of objects can be handled in a single batch job.
