Yes, it's used by many companies in production. There's a partial list here: https://www.datomic.com/customers.html

to be honest the testimonials are terrible. > “Datomic added to DynamoDB was the only option that didn’t force us to sacrifice features or add the expense of developer time. Without it, we would have had to push back a lot more, as the features would have been too difficult.” ( https://www.datomic.com/the-brigades-story.html ) like, what? effectively useless information. some of the other testimonials mention keeping…

It's not simply revision history, it's a complete record of everything with time, without re-architecting your data or app. IIRC datomic structures your data so that all transactions and state have a time dimension so you can go forward or back in time trivially (no special query, no temporal sql, etc.)

They say it's under the Apache 2 licence, so it is open source. EDIT: I was wrong. They actually released binaries under the Apache licence, not the source code. Which is, mildly said, deceptive. I don't even have an idea what that actually means.

They licensed the binary under Apache. It's a publicity stunt.

Making your product available for free isn't a publicity stunt, it's a huge step for a business. And, in practice, it's not that much different for the average user if only the binaries are Apache licensed. When was the last time you needed to open up the Postgres source code and modify something?

Aside, I remember HN in 2009 or so where Clojure was a daily homepage staple and Rich Hickey was putting out his talks about Clojure and code design. I watched a lot of that and used Clojure fulltime for five years. Wonder what he's up to these days.

Oh, that's today and tomorrow. I had been waiting for that, I could have sworn earlier this year they said there was going to be a live stream available. Maybe it didn't pan out.

Edit: Oh, there are streaming tickets for $20.

Datomic LOOKED cool 10-12 years when it first came out. But they started from day 1 with a price, so most people, me included, just passed over it.

I think they went way too fast to commercial, and needed to go a freemium model to actually get market share.

They say the binaries are being made under Apache 2. They don't say anything about the source code being published. That's why (to me) this is so interesting. I've never seen binaries released without source code before.

We used to call it Public Domain and Shareware (with variations like Coffeeware, Beerware, Postware,...)

It seems that they give the binaries for free but they won't release the source code. Can somebody explain to me what's the point of keeping the source closed in this case? I really can't think of any reason

Licensing issues, keeping the door open to making it not free again, greed, lack of understanding from management/lawyers/whatever, not wanting to deal with contributions (though here you can do what SQLite does), false sense of security, etc.

> Datomic Cloud will be available on AWS Marketplace with no additional software cost.

This is cool as well. It's a CloudFormation template based product you can deploy from AWS Marketplace.

Not complaining about the actual announcement itself here: seems pretty sweet all things considered, But: the "Is it Open Source?" section should lead with "No." It's not a complicated question, and it's not a complicated answer. I think it's weird to talk about having "all the same rights" without explaining why that matters particularly (it does matter, it's just not explained much!) but it is somewhat tangential t…

I felt the exact same thing. I was pretty sure the answer was "No" but they were too chicken to write it.

Were they hoping that people wouldn't notice?
