Being a better developer with Explain

Room: Auditorium


Developers use ORMs and here the question is not "is it good or bad" nor is it to convince them to rewrite years of technical debt but to show them that queries can be optimized by understanding what is happening behind their code. So any developer at the end of the talk should be able to know: - where to find the queries executed by the ORMs - To understand the different algorithm of filtering, sorting and joining. So basically, understand the output of a simple explain.
