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

**(True or False)** In the context of data processing, when something is slowing down or stopping, the flow of data is called back-pressure.

(True or False) In the context of data processing, when something is slowing down or stopping, the flow of data is called back-pressure.

**(True or False)** A stage can also have multiple instances of itself.

(True or False) A stage can also have multiple instances of itself.

________ is an Elixir behaviour to exchange events with back-pressure between Elixir processes.

________ is an Elixir behaviour to exchange events with back-pressure between Elixir processes.

**(Select all that apply)**  ________ can receive events and use them to do useful work. 

(Select all that apply) ________ can receive events and use them to do useful work.

Which stage is the beginning of a data processing pipeline?

Which stage is the beginning of a data processing pipeline?

**(True or False)** The producer stage receives events created by the consumer.

(True or False) The producer stage receives events created by the consumer.

**(True or False)** Complex use cases may require a data processing pipeline with a consumer stage, one or more producers, and several producer-consumers in between.

(True or False) Complex use cases may require a data processing pipeline with a consumer stage, one or more producers, and several producer-consumers in between.

Using multiple consumers to process events one by one, concurrently, is a very useful technique. To make this task even easier, GenStage comes with a special type of supervisor called_________.
