Welcome back! In this lesson, we will dive into Redis Streams — a powerful feature used for processing streams of data. This lesson will guide you through the basics and show you how Redis Streams can be essential for high-performance applications.

In this lesson, we'll learn about streams in Redis and how they can be used to handle continuous data flows. We'll learn how to create streams, add events to them, and read events from them.

Streams are a powerful data structure that allows you to process real-time data efficiently. Here are a few real-world scenarios where Redis Streams can be useful:

• Chat Applications: Streams can be used to handle messages in real time.
• Monitoring Systems: Streams can be used to process logs and events.
• User Activity Tracking: Streams can be used to track user actions in real time.

Let's dive into the details!

Here’s a quick preview:

• To add an event to a stream, you can use the xadd command.
• To read events from a stream, you can use the xrange command.

Let's see how these commands work in practice.
