PubNub Realtime Connected System

This plug-in uses Pubnub to handle real-time use cases such as the ones listed below.

Real-time Use Cases:

Real-time dashboards and interfaces
- Case handler working on support cases (cases record) can immediately see the new cases registered without refreshing their screen
- For any long-running asynchronous process, the user need not to refresh the screen to see the status as the updates can be sent real-time to the user's view
- See the real-time progress of batch processes
- See the status of a person, tasks working on different screens using PubNub presence API. The status can be as granular as getting an update when the user starts typing
- Add the power of collaboration to any Appian interface. Example - two persons collaborating in Google Docs
- Build Real-time feeds, activities, and notifications for your application
Real-time Maps
- Bring data from any source/ stream publish on a channel and see the real-time maps
- Build Geofencing, geocoding, geo hashing, directions and other powerful features in your application
Live Visualizations
- Bring streaming data and push it to Charts and Graphs
- Live auctions, financial stocks, and indexes, or scoreboards, send and publish updates to UIs in an instant
- Show real-time updates in Appian from Any IoT device
