Streaming Lite is a light-weight version of the Smart Data Streaming (“SDS”) server designed to run on IoT gateways to process data close to the source. A great example use case for applying complex event stream processing on the edge is a Worker Safety demo that the SAP IoT team has built in cooperation with Intel. In this reference sample, data from gas, motion and heart rate sensors is continuously processed through a Streaming Lite project to detect and react to unsafe situations. The first level of alert is generated when a dangerous gas level is detected. In this case an alert is generated for both the workers to evacuate the area and for the supervisor initiate a response. The second level of alert is generated when the pattern of a dangerous gas level is detected followed by detecting from the motion sensor that the worker is now prone. This combination of events results in a more urgent alert to respond to the immediate worker safety event.
Intel has provided a solution brief titled Intel and SAP IoT Bring Actionable Insights to the Edge that describes this reference use case in more detail.
To help you learn how to start building Streaming Lite projects, we have put together a comprehensive set of tutorials available in Learning how to use Streaming Lite with HANA Smart Data Streaming.
