Spring.io Barcelona May 2019 - Real Time Investment Alerts @ ING using Apache Kafka & Spring Kafka.
By Tim van Baarsen & Marcos Maia
Nowadays our customers are expecting real time interactions with investments products and services we deliver at ING Bank especially because financial market fluctuations can have a direct impact on the investments performance of our customers.
In this talk, we present how we deal with the massive stream of price updates on stocks and how we leverage many features of Apache Kafka and Spring Kafka to improve and simplify our solutions. From simple producer / consumer up to advanced usage of streams we strongly rely on Kafka to solve our functional and non functional requirements delivering high quality, real time stream processing software that is reliable, precise and extremely valuable to our customers.
Main challenges of our project One of the main challenges of this project was to deal with a massive continuous stream of stock price updates and matching them against thousands of alerts created by our customers and still keep up with sending real time alerts to them.
