for others curious

ParadeDB - AGPL License https://github.com/paradedb/paradedb/blob/dev/LICENSE

Hydra - Apache 2.0 https://github.com/hydradatabase/hydra/blob/main/LICENSE

also hydra seems derived from citusdata's columnar implementation.

Don't feel bad, lots of people get bitten by not reading all the way down to the bottom of their readme: https://github.com/hydradatabase/hydra/blob/v1.1.2/README.md... While Hydra may very well license their own code Apache 2, they ship the AGPLv3 columnar which to my very best IANAL understanding taints the whole stack and AGPLv3's everything all the way through https://github.com/hydradatabase/hydra/blob/v1.1.2/columnar/...

the only additional requirement that the AGPL introduces is that if you modify the AGPL software, you have to provide people who can access it over the network the code.

If you just use a pre-built package, the AGPL has the exact same requirements as the GPL.
