Event Notifications

NOTE: This feature is not available in NCache Express and Professional edition.
NCache allows client applications to register to be notified whenever add, insert or remove operation is performed against any or selected cache keys, or when some custom event occurs. Similarly, NCache provides events that are fired based upon cluster status. This section is about availing such notifications.
