L13: Coroutines vs Traditional Asynchrony

Lesson in Preparation (WIP)

This lesson is currently undergoing pedagogical drafting and development. It will soon be available with detailed visual diagrams, in-depth explanations, and its corresponding milestone in the AI Chat CLI incremental lab.

What will you learn in this lesson?

In this lesson we will explore:

• Deep Theory: Operating system threads (Java Threads) vs Coroutines (lightweight threads), non-blocking suspension vs thread blocking, and structured concurrency.
• Under the Hood: Memory footprint comparison on the JVM (~1 MB stack per OS thread vs tens of bytes per coroutine) and how the JVM schedules coroutines across underlying worker thread pools.
• Incremental Lab (AI Chat CLI): Profiling I/O blocking in the terminal console and designing cooperative concurrent background tasks.
