Take care of the queries

Goals

There are always several ways to write a query, and several ways to get the same result. But not all ways are necessarily equivalent. Analyzing and measuring are the two key words to understand what’s going on under the hood and to code in the most efficient way. This session will illustrate these different options with concrete examples and will propose a study of the exchanges generated with the server.
