ZIO Streams Part 1 (The Channel Type)

A talk from the Zymposium meetup. Streams in ZIO 2.0 have the same API you are used to, but under the hood, they are now powered by channels. We'll look at what channels are and how to use them to implement our own stream operators.

ZIO Streams Part 2 (Using Channels)

In this episode, we will continue our exploration of streams in ZIO 2.0 learning how to implement our own channel operators as well as stepping back and looking at higher-level stream operators.

ZIO Streams Part 3 (Streaming Sandwiches)

In this episode we're coming back to streams, looking at how we can use our new knowledge of channels to solve some real-world problems.

ZIO Streams - Final Part (Fan In/Fan Out)

In this episode, we will be looking at concurrent operators that let us "fan out" and "fan in" streams. Let's do this!
