Abstract:
An apparatus for file change notifications includes a notification creation module that creates, on a first local node, a file change notification message in response to a client creating, deleting, and/or modifying a file system item addressed through a file path. The first local node notifies associated local client processes representing clients connected to the first local node and flagged to receive file change information. The apparatus includes a node identification module that checks a global node for second local nodes flagged to receive file change information for the file path and a notification distribution module that sends a file change notification message from the first local node to the second local nodes in response to receiving identification of the second local nodes. A second local node notifies associated local client processes representing clients connected to a second local node and flagged to receive change information for the file path.
