Abstract
Disclosed is a distributed storage system and methods for providing real-time localized data access from different storage nodes of the distributed storage system. Providing the localized data access may include tracking access frequencies with which a file is directly accessed from the different storage nodes, storing a source copy of the file at the first storage node in response to the access frequency at the first storage node being greater than the access frequency at the other storage nodes, caching the file at a second storage node, transferring control over the source copy from the first storage node to a third storage node based on a change to the access frequencies, and validating the cached copy of the file at the second storage node against the source copy at the third storage node prior to responding to a request for the file from the second storage node.
