In this article, we look at Apache Kafka and NATS Streaming, two messaging systems based on the idea of a commit log. We’ll compare some of the features of both but spend less time talking about Kafka since by now it’s quite well known. Similar to previous studies, we’ll attempt to quantify their general performance characteristics through careful benchmarking. The purpose of this benchmark is to test drive the newly released NATS Streaming system, which was made generally available just in the last few months. NATS Streaming doesn’t yet support clustering, so we try to put its performance into context by looking at a similar configuration of Kafka. ...

“Taco Bell Programming” is the idea that we can solve many of the problems we face as software engineers with clever reconfigurations of the same basic Unix tools. The name comes from the fact that every item on the menu at Taco Bell, a company which generates almost $2 billion in revenue annually, is simply a different configuration of roughly eight ingredients. Many people grumble or reject the notion of using proven tools or techniques. It’s boring. It requires investing time to learn at the expense of shipping code. It doesn’t do this one thing that we need it to do. It won’t work for us. For some reason—and I continue to be completely baffled by this—everyone sees their situation as a unique snowflake despite the fact that a million other people have probably done the same thing. It’s a weird form of tunnel vision, and I see it at every level in the organization. I catch myself doing it on occasion too. I think it’s just human nature. ...
