mdfs::MFile Class Reference

A distributed file is not necessary stored locally LocalPath could point to the local file or be empty A local path could be different that the real path on the server since the file structure on the server could be simply stored in a DB, not on the HD By convention a directory is always followed by a slash (/). This help when we use a path as a unique key in a DB, so /mystuff (directory) and /mystuff (file) can each be a key because /mystuff (dir) must be rewritten /mystuff/ and is therefore different than /mystuff (file).

Detailed Description

A distributed file is not necessary stored locally LocalPath could point to the local file or be empty A local path could be different that the real path on the server since the file structure on the server could be simply stored in a DB, not on the HD By convention a directory is always followed by a slash (/). This help when we use a path as a unique key in a DB, so /mystuff (directory) and /mystuff (file) can each be a key because /mystuff (dir) must be rewritten /mystuff/ and is therefore different than /mystuff (file).

Todo:

remember from what host it is coming? Kind of contradictory with the concept of "naming": -Location Transparency: the path name does not reveal the file location -Location Independance: files can be moved and al references to them continue to be valid
