I’m not the only one who thinks MariaDB would have been the more informed decision.
I have been reading this exchange in view of other major deployments, where database selection is key, and MariaDB, with its truly open concept, growing support and user base, plus ever improving scalability are key.
MySQL is not closed source, but dual-licensed, so if you want to scale up, you have to pay. In this regard, all the above comments that are highly critical of the Ghost team’s choice to stick to MySQL are appropriate, future-proof and by no means fallacious!
I will say that use of Knex.js does seem to support pure SQL (SQL engine agnostic), which is good. Kudos on that.
