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.

# GenStage producers

The `Broadway` library is an excellent choice when working with popular message brokers. However, it's not limited to just that. `Broadway` could be useful in a wide range of use cases where we need a data-processing pipeline with built-in dynamic batching. We only have to bring our own `GenStage` producer and `Broadway` will happily do the work for us. We'll see how this works by revisiting the `scraper` project one last time. We already used `GenStage` and `Flow` to implement it, so it will be great to implement another version using `Broadway`, for comparison.

# Replace `:flow` with `:broadway`

Let's start by replacing `:flow` with `:broadway` in the dependencies' list:


Learn to use GenStage for processing data pipelines with dynamic batching.
