I’ve worked with many libraries and frameworks and I haven’t seen transactions by default. Given how easy it is to deadlock yourself this way, for instance by naively making batch reads in random order. I doubt many libraries would make transactions the default. For instance in rails and django you need to explicitly specify a transaction. Can you give an example of a framework that turns off auto commit by default and instead runs it at the end of http requests?
