• Event processing with Elixir
• What problems may arise when processing events
• How GenStage can solve them

In this talk we’ll look at GenStage, an Elixir library to structure demand-driven data flows.

The talk will be example-driven: we’ll start with a data-pipeline application written without GenStage and put it under heavy load. By doing that, we’ll have a first-hand account of the issues that GenStage aims to solve.

We’ll then look a revised implementation of the same data pipeline that uses GenStage to see how it solves the issues found in the original version of our application.
