I find the the amount of traffic and comments articles with this message generate quite amusing, given the article can be boiled down to: don't use tools like Cassandra, Kafka, etc. until you've thought through whether they are the right tool for your use case. That last part is often forgotten -- these tools may not always be the right tool for the job, but SOMETIMES they are, regardless of your scale.

Well, duh.

The corollary is: if you're using one of these tools, and you HAVE thought through your use case and reasons, don't get defensive about it. If challenged by those with lesser knowledge after reading an article like this, calmly and rationally explain your reasoning. And like any technology choice, be prepared for someone else to offer another option you weren't aware of, with better reasons.

Again, duh.
