When Funding Circle needed to scale its lending platform, we chose Kafka and Clojure. More than a programming language, Clojure is an interactive development environment with which you can build up an application function by function in a continuous unbroken flow. Since 2016 we have been developing our lending platform using Clojure and Kafka Streams, and today we process millions of transaction dollars daily. In 2018 we released "Jackdaw", our open-source Clojure library for working with Kafka Streams. In this talk, attendees will learn a radical new approach to building stream processing applications in a highly productive environment--one they can use immediately via Jackdaw or apply to their favorite programming system.
