Did you know that PayPal’s product performance tracking platform processes over 10 billion messages per day making it one of the busiest systems in PayPal? Its end-to-end Reactive data processing pipeline consists of Akka Streams, Kafka, Spark and Druid, which posed a number of technical and the organizational challenges, including converting this well-established team into a Reactive mindset.

In his talk, Turning PayPal’s Product Performance Tracking platform Reactive, End-to-End,  at Reactive Summit in Montreal on October 23, Michael Zeltser, senior member of technical staff and architect at PayPal, will share a narrative useful for both beginner and intermediate audiences, builders and managers alike, that will help contextualize conceptual and practical aspects of switching to reactive systems.

In advance of his talk, we spoke to Michael about his path to Reactive systems, the future of Reactive, and why his job is never boring.
