  Q: What would happen when multiple users download large files from the st=
ore? A: Db``Data``Store: It depends on whether the copyWhenReading option i=
s enabled or not (see there). File``Data``Store: The same file would be ope=
ned multiple times. The file would be in the operating system / file system=
 block cache, so that wouldn't be a problem.

 of the data store is that the content is immutable.
