Using Jaeger tracing, I’ve been able to answer an important question that nearly every Apache Kafka ® project that I’ve worked on posed: how is data flowing through my distributed system? Before I discuss how Kafka can make a Jaeger tracing solution in a distributed system more robust, I’d like to start by providing some context.
