Example: NV
NV (Network Variable) is an extension of the nsv shared variable interface in AOLserver:
- A client (e.g., front end server) can request streaming updates from a backend server
- Client variable interface remains the same
-
NV is useful for several applications, e.g.:
- Sport scores: Continuous updates, streamed incrementally
- Movies Top 10: Recurring bulk-updates of aggregated data
- Meta data: Occasional updates of data which must be consistent on all client, e.g., list of known cities
