Building Concurrent Data Pipelines with Elixir and GenStage

Modern software systems must process massive amounts of data concurrently without exhausting system resources. Elixir provides a powerful concurrency model, but managing the flow of data between producers and consumers requires a structured approach. This text-only course guides you through the core mechanics of data pipelines using GenStage, Elixir's premier specification for exchangeable stages. You will learn how to prevent system crashes under heavy loads by implementing structured flow control. By reading through clear code examples and conceptual breakdowns, you will transform from an Elixir developer into a pipeline architect capable of handling complex data workflows. What you'll learn: Understand the foundational architecture of producers, producer-consumers, and consumers; Implement back-pressure mechanisms to dynamically control data flow and prevent memory overload; Build scalable multi-stage pipelines to process data concurrently; Manage state and supervision trees to ensure your pipelines are fault-tolerant; Apply modern Elixir testing patterns using mock data sources to verify pipeline behavior. The course starts with essential concurrency terminology and foundational pipeline concepts before guiding you step-by-step through practical implementation patterns, supervisor configuration, and testing strategies. This course is designed for beginner to intermediate Elixir developers who want to transition from basic concurrency to structured data processing; no prior experience with GenStage is required. Start reading today to build resilient, self-regulating data pipelines in Elixir.
