Real-Time streaming in SAP Design Studio is now possible with the new SAP Event Stream Processor or SAP HANA Smart Data Streaming (as part of SAP HANA SPS 09) and SAP Design Studio 1.4.
I started drafting this blog with some screenshots and then realized it might be better to show it as a short video demo instead. So, I created a video demo of an overview on Real-Time (Push Case) and near Real-Time (Pull Case) using SAP ESP 5.1 SP9, SAP HANA SPS 09, and SAP Design Studio 1.4.
Real-Time and Near Real-Time Streaming in SAP Design Studio
Real-Time (Push Based):
SAP ESP enables you to create and run your own complex event processing (CEP) applications to derive continuous intelligence from streaming event data in real-time. With the new SAP Design Studio 1.4 data is streamed into the dashboard in Real-Time.
For this demo, I created a macro that generates random numbers every second, and this data is loaded into SAP ESP and streamed into SAP Design Studio in Real-Time.
Near Real-Time (Pull Based):
You can create near real-time visualizations when connected to SAP HANA or SAP BW (Pull Based) data sources by using the Timer custom component. The Timer custom component allows you to set an interval in milliseconds.
So in this demo, data is loaded into SAP HANA tables in real-time and the dashboard is built on top of an Analytic View. Data is refreshed every 15 secs using the Timer component.
If you don’t really want to load the data into SAP HANA, you can use the Smart Data Access and create a virtual table from this stream.
Real Time Dashboard in SAP Design Studio
Context:
- You need an instance within SAP ESP 5.1 (SP09) and a project running.
- An Analytic View in SAP HANA.
- You need the Real-Time package installed in Design Studio 1.4.
