Please list a few successful open source AGPL projects with a significant user base.

I agree. I think the AGPL license perceived risk played a significant role in RethinkDB's lack of user acceptance.

> it seems like you have misunderstood what the AGPL does.

I've read the AGPL license. I disagree with your interpretation.

> How many people using RethinkDB are changing its code?

That's not the point. If you're even using the software the other software components would also be bound by the AGPL license.

> I don't know if this is a sound legal interpretation of the AGPL though.

Exactly. AGPL was explicitly created to make all clients of the software be bound by its license. To say that the drivers have a different license makes no sense at all.

As long as RethinkDB is AGPL most will just stick with postgres.

Is it possible (or likely) to get the creditors of Rethink to change the license?

Affero General Public License is much more restrictive than GPL. People are not comfortable using it in a commercial setting.

KDB is not really a database as much as it is an RPN calculator with a lot of memory.

That's an unfortunate license choice. No one will use it.
