Overview

A large number of use cases span beyond a single request-reply, require tracking of a complex state, respond to asynchronous events, and communicate to external unreliable dependencies. The usual approach to building such applications is a hodgepodge of stateless services, databases, cron jobs, and queuing systems. This negatively impacts developer productivity as most of the code is dedicated to plumbing, obscuring the actual business logic behind a myriad of low-level details.

This cookbook is for developers and engineers of all levels looking to understand how polling works in Cadence. The recipe in this book provides “Hello, World!” type examples based on simple scenarios and use cases.
