So much criticism here! I've read a lot about Kafka over the last few years and I wish I had read this article earlier -- even basic questions like "Can Kafka store data persistently?" are not adequately answered in many intros to it. That said, I do find the tutorial flip-flops a bit in target audience. It's mainly "this is what Kafka is", but sometimes has weird asides like "This is how to optimise Kafka" (redundancy, number of partitions, etc) which are pretty distracting from the more fundamental points.
