> Clients can fetch information from registry and cache it locally or in memory for performance reasons. They would like to be notified when update to this semi-static information happens. An use case like refreshing xbaya registry panel described in https://gateways.atlassian.net/browse/PARAMCHEM-114 will benefit from this feature. 
> Kishore from Apache Helix community has mentioned similar registry client notification used within linked in with a possibility of being open sourced. We need to check if this is available in any helix components and re-use the software or the concept.
