Wrapping Up

Elixir processes

We’ve come a long way from running synchronous code and patiently waiting for it to complete. We covered Elixir processes and used the Task module to work concurrently and in parallel, easily avoiding timeout errors and unexpected exceptions.

Supervisors

We also learned about supervisors, which are the foundation of building fault-tolerant Elixir applications.

Limitations of the Task module

Although the Task module is powerful and versatile, it is only useful for running one-off functions concurrently. As a result, Task processes are short-lived and exit as soon as complete.
