Talks 1
In this talk I will present material from my academic paper "How Good Are Query Optimizers, Really?", which was published at PVLDB 2015. This tries to shed light on the query optimization process.
In addition, I will talk about some experiences building a query engine that compiles SQL queries to machine code.
