My current job is maintaining Kafka infrastructure, dozens of clusters. I literally don’t understand how it got so popular. It is by far the least reliable software I have ever experienced. We hit so many bugs and weird edge cases that essentially cripple the entire cluster and stop all producing. Zookeeper in addition has been a constant source of headaches.
