/**
 * This is some code extracted from TimeOut codebase, demonstrating:
 * - Use of tag typed to avoid mixing session of different DB
 * - The use of the Reader Monad to compose Actions together and defer the choice of async/sync computation
 *
 * I remove the part where we can say if our operation are read only or not (to use different connection), in order to
 * make things easier.
