Notification for New Arrival of Timeseries Data


Currently, to fetch Time Series data, an Insights Hub application would have to query all Asset instances, compare the timestamps, find the latest Time Series data and update the application. This would involve multiple requests through Industrial IoT Gateway which is expensive, not optimal or customer friendly.

With subscription based notification, 3rd party applications will get notified by Insights Hub on new Time Series data arrival for concrete Assets & Aspect combination in a time range of 1 minute. This mechanism enables customer when to poll the Time series data. Moreover this improves the usability of Insights Hub Services and user experience for the developers.

To create and publish App for consuming Timeseries data arrival notification, refer to How to Subscribe to notifications from Insights Hub for new data arrival
