Continuous Query

Distributed applications that require rapid changes in data demand synchronization of caches and clients with the same pace. With synchronization of cache, it is also essential that all clients are able to share information related to some specific data set whenever any change occurs in it.

Continuous Query is provided by NCache for runtime monitoring and sharing of data related to an observable data set. This allows applications to be notified of all changes that occur within the queried result set in the cache.
