Abstract

Systems and methods that supply poll based notification system in a distributed cache, for tracking changes to cache items. Local caches on the client can employ the notification system to keep the local objects in sync with the backend cache service; and can further dynamically adjust the “scope” of notifications required based on the number and distribution of keys in the local cache. The server can maintain the changes in an efficient fashion (in blocks) and returns the changes to clients that perform the appropriate filtering. Notifications can be associated with a session and/or an application.
