Abstract
The described technology is generally directed towards domains that data services can use to collect files of a global filesystem namespace into groups. A data service (a domain patron) creates a domain, e.g., for a particular directory, and a domain manager associates files under that directory with domain membership information. Thereafter, the data service can use the domain membership information associated with a file to determine whether to include that file in a data service operation. In one implementation the membership information is maintained in file metadata, facilitating fast and efficient retrieval of the information in near constant time. Exclusion from a domain, hard links, renames and alternate data streams are among the various aspects supported by the domain technology.
