@kjenkins presented at the Bangalore Java User Group recently, and it was a sight to behold. Kris live-coded a dashboard application using Apache Kafka, ksqlDB, Websockets, and React, in about 45 minutes, all while answering questions along the way!
Not only did we get a great example of the power of Kafka and ksqlDB, but we also saw what a great fit Websockets are with event-streaming applications.
I will give you one warning before you watch the presentation recording here, you may end up wanting to learn emacs by the time it’s done!
