Connecting 2.570 grocery and drugstores in real-time at REWE.

REWE International AG is known as being one of Europe's leading grocery trading- and tourism companies. It is Austria's number one local grocery and drugstore supplier reaching the lives of 1,9 million Austrian customers every single day in more than 2.570 stores. In order to integrate the data of their shops in real-time, we supported REWE International AG by setting up their streaming solution using Apache Kafka.

Every store has data that wants to get connected.

A ton of events are happening every hour in each REWE International AG store. Event data contains valuable insights. Making this data available in an easily accessible, realtime fashion, opens up new dimensions in respect to data analytics and integration.

Our Contribution

In order to reach the goal of analysing event data and deriving valuable insights from said data, we helped REWE International AG to build an event streaming solution using Apache Kafka. By building this solution, we put a strong focus on automation in respect to the infrastructure as well as concerning the creation of certain event types (topics). Automation, especially regarding the infrastructure, allowed us to architect a system that is not just particularly responsive and resilient but also actually scalable.

Technical Highlights

To set up real-time data integration on this scale, the autoscaling of the underlying infrastructure as well as the solution itself definitely was one of our biggest achievements. In addition to that, the automatic creation of topics helps the development team to be able to initiate the processing of new events in a very quick manner. We are proud that we got the chance to architect this part of the software ecosystem together with REWE International AG, from the sketching-process to the production.
