Galera cluster for MariaDB

[matthieu-robin]

As a customer, I would like to choose between Galera Cluster and Replicated DB. Mariadb-operator can handle it: https://github.com/mariadb-operator/mariadb-operator/blob/main/docs/HA.md and automatic failover with MaxScale.

Thanks a lot

Unfortunately MaxScale is licensed under no-free Business Source License, and we can't integrate it as-is into Cozystack. Are you interested in automating license handling in Cozystack for MaxScale, or we can consider free alternatives (if any?)

Sorry to ask a stupid question...

If MaxScale offers a good technical option, and it is free to use in many cases, then what is the bad thing about integrating that?

I suppose that I'm of the opinion that almost anything that moves commercial users of otherwise free-software into paid-users is a massive net positive.

Even for the CozyStack business model, if certain options during setup channel more enterprise users towards a option where they are more directly pressured into providing financial support in exchange for their use, I just don't see how it's a bad thing.

Please help educate me.

Hi @erwin , thanks for asking. The concern with software under non-free licenses is that by including it in Cozystack we may be in violation of the terms under which it is available. One would have to get express permission from the copyright holders which, if revoked, would be a nightmare for whomever who has to remove it retroactively from the entire git history.
