Is this free and open-source in the sense that we can host it on our own infra with no license fees? Is there any guide or example for deploying this in a AWS environment with typical data sources like S3 data lake (CSV/Parquet/Delta) and Redshift?
The related docs will be published soon, we are working on connecting RATH to more infra now, you can join the discord to the latest discussions. https://discord.com/invite/Z4ngFWXz2U
But also, the git repo has LICENSE with the AGPL, as well as LICENSE2 which just has some names followed by all rights reserved. It's a bit confusing, if there is dual licensing or some of the files are licensed differently maybe you should explain that in the LICENSE file, even if it means referencing a separate AGPL file.
In any case it looks pretty neat, I think I'll give it a try.
