Free as in beer. Not free as in speech.

> Is it Open Source?

Datomic binaries are provided under the Apache 2 license which grants all the same rights to a work delivered in object form.

Datomic will continue to be developed at Nubank, where it is a critical piece of our infrastructure.

What is Datomic, you ask? It's a database written in Clojure. https://hn.algolia.com/?q=datomic

  Datomic is an operational database management system - designed for transactional, domain-specific data. It is not designed to be a data warehouse, nor a high-churn high-throughput system (such as a time-series database or log store).
  It is a good fit for systems that store valuable information of record, require developer and operational flexibility, need history and audit capabilities, and require read scalability.

The price is certainly right, but has anyone used this in production? What was your experience like?

https://www.datomic.com/get-datomic.html still seems to show licensing fees at the time of this comment.

Only the binaries are made available, not the source, which is interesting.

I guess they don't claim to be open source, they're claiming to be free, which is - in itself - awesome.

Last time I checked, you couldn't push binaries to maven central, without also releasing the source. That may have changed.

I find that answer confusing. I don't think I've ever seen binaries being licensed under Apache 2 without the relevant source code before.

Yes, it's used by many companies in production. There's a partial list here:

Yeah, it's a complete bullshit move. Mongoose OS (an embedded iot Plattform not the db) does something similar. It's extremely weasely and doesn't instill trust at all.
