Redis Basic Data Management: Key-Value Operations and Atomic Counters Tutorial

Redis is the backbone of modern high-performance applications, serving as an ultra-fast, in-memory data structure store. If you've been looking for a practical, hands-on way to learn Redis without wading through hours of video lectures, the LabEx Redis learning path is designed for you. This structured roadmap takes you from zero to proficiency, starting with the absolute fundamentals of data storage and management. We provide an interactive, dedicated Redis playground where you execute real commands and see immediate results. Let's dive into the foundational labs that will quickly equip you with essential Redis skills.

Basic Data Management in Redis

Difficulty: Beginner | Time: 20 minutes

In this lab, you will explore basic data management techniques in Redis. You'll begin by learning how to increment and decrement numerical values using the atomic INCR and DECR commands, suitable for counters and rate limiters. You'll connect to the Redis server using redis-cli, set initial values, and then increment and decrement them, verifying the results with the GET command. Furthermore, you will learn how to retrieve all keys stored in Redis using the KEYS command.

Basic Key-Value Operations in Redis

Difficulty: Beginner | Time: 20 minutes

In this lab, we will explore basic key-value operations in Redis, focusing on how to interact with Redis as a data store. We'll use the redis-cli command-line interface to connect to the Redis server and perform fundamental operations. We will learn how to set and retrieve key-value pairs using the SET and GET commands. Furthermore, we will practice setting different key-value pairs to solidify our understanding of these core operations.
