## Introduction Redis Streams is a data structure in Redis that provides a way to store and process streams of data. It allows you to append new data to the stream, and retrieve and process the data in the order it was added. ## Quick Start To use the Redis Streams Playground, follow these steps: 1. Access the playground environment on the GetVM website. 2. In the terminal, you can interact with Redis using the `redis-cli` command. 3. Use the Redis Streams commands, such as `XADD`, `XRANGE`, `XREAD`, and `XGROUP`, to create, read, and process the data in the stream. 4. Experiment with different use cases and scenarios to learn how Redis Streams can be applied in your projects. The GetVM Redis Streams Playground provides a Container-based VM with 1 core and 2GB RAM, and up to 10GB of storage. VMs can be used for 30 minutes, with a 20-minute reminder before expiration.
