Infinity in the palm of your hand

1 hour 

Infinite data is a large concern in streaming, but as a concept it’s impossible to fathom. In this tutorial, we’ll develop an intuition for infinite streams in fs2. We’ll see how fs2 describes infinite processes, and build a model for understanding them.

No leftovers: Working with pulls in fs2

1 hour 

fs2 is an excellent functional streaming library with a rich toolbox for transforming streams. But sometimes we need a transformation that’s outside that box. In this tutorial we’ll learn how to write custom transformations using the fs2.Pull datatype. By the end of it you’ll be able to write every stream transformation you can think of.

Understanding thread pools through cats-effect

1 hour 

Could not find an implicit IORuntime. is a common error when using cats-effect. But what is an IORuntime, and how should we use it? In this tutorial, you’ll use cats-effect 3 to explore the basics of thread pools, execution contexts, and blocking. You’ll see why the cats-effect IORuntime.global is the best model for your application.
