Most engineers don’t think that concurrency is distinct from programming. Data processing includes transforming information in some way, like reporting, data aggregation, or analytics. On the other hand, concurrency involves significantly improving performance.

This course is designed to help you navigate the world of concurrency tools available in the Elixir ecosystem. You’ll explore popular modules and libraries like GenServer, GenStage, Flow, and Broadway. You’ll be able to ingest data, set up pipelines, and run concurrent processes with Elixir.

By the end of the course, you’ll have a wide range of new techniques to simplify your product, improve code performance, and make your application more resilient to increased workloads.

Concurrent Data Processing in Elixir

## The `Task.async/1` task

To retrieve the result of a function, we use **`Task.async/1`**. It returns a `%Task{}` struct which we can assign to a variable for later use. We can give it a try in IEx like this:

This is the executable command:

Learn to use Task.async, which has the property to return a struct containing the executed task’s result.
