I read various interpretations of the AGPL and some people think it’s not the case. MongoDB used to be AGPL and I believe most people didn’t interpret the license as everything calling the database must be AGPL, and then everything calling the thing calling the database too, that recursively until the entire world must be licensed under AGPL.
We'll see when AGPL gets tested in court. Until then I suspect legal departments will continue to treat AGPL, and even GPL (because of on prem), as a viral license which could require disclosing all their source.
No

No
No we won't see it tested in court? Or legal departments won't consider it a viral license?

#35We tried it for a payment system, the concurrency issues where an absolute nightmare to deal with.Especially in combination with Hibernate. In serializable isolation level some queries would just never finish, no matter how many retries you gave it.

#36Launched it on a t3.nano (0.5GB RAM) in a single node configuration for two extremely small tables - got oom kills in couple of hours.
Launched on a t3.micro (1GB RAM) - same.
Launched on a t3.small (2GB RAM) - finally it works and doesn't crash.
So, min 2GB RAM to serve about 10 (as in: ten, not thousands) records queried every other second.

What does that mean? What service do you have that is disallowed? We are evaluating it and are finding the license page confusing. Yugabyte seems friendlier but it seems even less talked about.
I used YugabyteDB. License was one thing: database is Apache 2 licensed and no strings attached, you can operate it as a service yourself. Not so with CockroachDB, what powerhour said. Other reasons: it’s Postgres code under the hood, not a rewrite, so you can use existing extensions. I have even contributed the support for FDWs, which I use in production.

Thank you for that feedback!

#39Haven’t used them in production because their license doesn’t allow operating as a service. I have used an alternative.
To be clear, you can use CockroachDB if you're a service.
What is prohibited, however, is you can't take CockroachDB and try and offer a hosted CockroachDB-as-a-Service to external organizations.
But if your organization has a DB-as-a-Service offering internally, you can totally add crdb to the mix (this is pretty common, as a matter of fact). If your org offers a service and its backed by crdb, you can totally do that, too.

The latter. Every large company on the planet uses Linux which is GPL.
GPL is widely used in SAAS because network users of SAAS aren't entitled to source. AGPL is different.
