Concurrent Data Processing in Elixir

Wrapping Up

Congratulations on completing this chapter! You’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 do work concurrently and in parallel, easily avoiding timeout errors and unexpected exceptions. You also learned about supervisors, which are the foundation of building fault-tolerant Elixir applications. A lot of the things we covered so far will appear again in the following chapters, so we have created a strong foundation to build upon.

Although the Task module is very 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 they complete. In the ...
