Comment Comment by mbrt Nice, thanks for the reference!BTW, the comparison was only to give an idea about isolation levels, it wasn't meant to be a feature-to-feature comparison.Perhaps I didn't make it prominent enough, but at some point I say that many SQL databases have key-value stores at their core, and implement a SQL layer on top (e.g. https://www.cockroachlabs.com/docs/v22.1/architecture/overvi...).Basically SQL can be a feature added later to a solid KV store as a base. parent mbrt 1 year ago
