If it wasn’t clear from the article, this is open source and available on Man’s GitHub page:

I used to work at man, so take this with a grain of salt, but I really liked this and have spun it up at home for side projects over the years.

I’m not aware of other specialized storage options for dataframes, but would be curious if anyone knows of any.

The license is the Business Source License, which is not open source: https://en.wikipedia.org/wiki/Business_Source_License

The current license says the terms shall change to Apache after two years a release has been available.

Not for me, but some might find it interesting.

Not sure if it's standard practice when using Business Source License, but seems to have additional terms too, like:

> BSL features are free to use and the source code is available, but users may not use ArcticDB for production use or for a Database Service, without agreement with Man Group Operations Limited. [...] Use of ArcticDB in production or for a Database Service requires a paid for license from Man Group Operations Limited

So not just "source available, go ahead and use it" but basically "free for personal use only".

Feels more feel free to use it as long you aren't a competitor

> Free as long as you aren't a competitor, or you use ArcticDB for anything we could consider "in production"

This is how I understand their text, and I wouldn't be super excited about trying to figure out exactly what "in production" means with their lawyers in court.

Yeah that’s fair, not open source, I was incorrect, though I think it’s more than personal use only. “Production use only” is doing a lot of heavy lifting and I don’t know exactly what that means (though could make a guess).

Need a licence apparently, source available.

Few doc choices are as annoying as using GIF to show code that i should read in 2 seconds.

Will improve.
