> There was no major effort to fork off MongoDB, Neo4j, Kafka, or CockroachDB when they announced their license changes. AFAIK people didn't take MongoDB seriously from the start, especially with the "web scale database" joke circulating. The Neo4j Community version has been under GPLv3 for quite some time, while the Enterprise version has always been somewhat closed, regardless of whether the source code was available on GitHub (the mentioned license change affected the Enterprise version). Regarding CockroachDB, I must admit that I've only heard about it on HN and don't know anyone who seriously uses it. As for Kafka, there are two versions: Apache Kafka, the open-source version that almost everyone uses (under the Apache license), and Confluent Kafka, which is Apache Kafka enhanced with many additional features from Confluent, and the license change affected Confluent Kafka. In short, maybe the majority simply didn't care about these projects very much, so there is no major fork. > It cannot be because the Redis and Elasticsearch install base is so much larger than these other systems, and therefore, there were more people upset by the change since the number of MongoDB and Kafka installations was equally as large when they switched their licenses. I can’t speak for MongoDB, but the Confluent Kafka install base is significantly smaller than that of Apache Kafka, Redis and ES. > Dana, Bohan, and I worked on this research project and startup for almost a decade. And now it is dead. I am disappointed at how a particular company treated us at the end, so they are forever banned from recruiting CMU-DB students. They know who they are and what they did. Call me a skeptic, but I can't see this as a fair approach. If your company fails for whatever reasons, you should not recruit the university department/group/students against your peers (I can't find that CMU-DB was one of the founders of Ottertune). Wrt Andy, here are [1] somehow interesting views from (presumably) previous employees.

There are production uses of MongoDB (Stripe comes to mind). But it is certainly not a popular choice there.

  MongoDB does over $2b in revenue (and growing by 20%) each year. There are a lot of production uses.

    In my experience, these are largely startups or non-production use cases. Also, MongoDB charges an arm and a leg and does not make it particularly easy to self-host (and many newer features are limited to their hosting).

  It’s sad, but there are a lot of companies using it. In all places I know (directly or friends) it’s being chosen as „easier”. Almost everyone ends up not knowing the real schema of data inside the database, but using Spring-magic they are already lost and not owning the data. Maybe the enterprise Mongo is not so widely spread (they earn much, because they are not cheap), but free version is IMO overused and popular :(

> Wrt Andy, here are [1] somehow interesting views from (presumably) previous employees. I am only seeing this now and I take the complaints about being "slightly racist and offensive" very seriously. I am checking with investors, former HR people, and co-founders. I was not made aware of any issues. If anything, I was overly cautious at the company. I was openly transparent with our employees about every direction the company was pursuing up until the very end. The complaint that "He thinks he knows everything about business" makes me believe this person is just trolling because I was always the first to admit in meetings that I was not an expert in how to run a business. We had to fire people because of inappropriate behavior, but not because I had strong disagreements with how to run the company.

  FWIW, as someone who had multiple friends who worked closely with Andy over 5+ years and at all stages of their career (both BS / PhD) those comments reek of someone with an axe to grind. All of the many anecdotes I have about Andy paint a picture of a great advisor and mentor. I suppose I should say "shenanigans aside", but if you can't separate his jokes from his academic side you need to develop a sense of humor.

> ... you should not recruit the university department/group/students against your peers ... As a student who chose to stay at CMU for a PhD because of this group, it is quite the opposite situation - you may also misunderstand the nature of the "ban" (students can still apply directly to the company). From the student perspective, we benefit from knowing the reputation of potential employers. For example: CompanyX went back on their promises so don't trust them unless they give it to you right away, CompanyY has a culture of being stingy, the people who went to CompanyZ love it there, and so on. So it's more like (1) providing additional data about the company's past behavior, and (2) not actively giving the company a platform. I personally find this great for students.
