Скачать или смотреть Debug Spark & Kafka Streaming With This FREE Playground

Stream processing with Kafka and Spark can be tricky, especially when debugging. That’s why I built a free streaming playground for you to experiment with producers, brokers, Spark executors, and database sinks. Check it out, play with different settings, and see how all the components interact in real time!
