Mastering Redis

Course Duration: 3 Days

Course Description:

This intensive 3-day course provides a comprehensive overview of Redis, an open-source, in-memory data store. You will learn about its core concepts, data structures, and practical applications. Through hands-on exercises and real-world examples, you will gain the skills necessary to effectively leverage Redis in your projects.

Target Audience:

• Software Engineers

• DevOps Engineers

• Data Engineers

• System Administrators

• Anyone interested in NoSQL databases and in-memory data storage

Course Objectives:

Upon successful completion of this course, participants will be able to:

• Understand the core concepts of Redis and its architecture.

• Effectively use Redis data structures (Strings, Hashes, Lists, Sets, Sorted Sets, Streams).

• Implement caching strategies using Redis.

• Utilize Redis for session management and rate limiting.

• Design and implement basic Redis-based applications.

• Understand Redis persistence mechanisms (RDB, AOF).

• Learn about Redis clustering basics.

• Troubleshoot common Redis issues.

• Integrate Redis with other technologies.

Course Outline:

Day 1: Redis Fundamentals

• Introduction to Redis

  • What is Redis?

  • Introduction to NoSQL databases

  • Redis architecture and key features

  • Installation and configuration

  • Redis Clients (e.g., Redis CLI, Python Redis library)

  • Data Structures: Strings (SET, GET, INCR, DECR, APPEND, etc.)

  • String operations (GETRANGE, SETRANGE, MGET, MSET)

  • Expiring keys (EXPIRE, TTL)

  • Hands-on Exercise: Basic String Operations and Key Management

Day 2: Data Structures & Applications

• Data Structures: Hashes, Lists

  • Working with hash fields (HSET, HGET, HGETALL, HMSET, HMGET)

  • Hash operations (HINCRBY, HEXISTS)

  • Pushing and popping elements (LPUSH, RPUSH, LPOP, RPOP)

  • List operations (LRANGE, LINDEX, LLEN)

  • Blocking operations (BLPOP, BRPOP)

  • Hands-on Exercise: Building a simple message queue with Lists

• Data Structures: Sorted Sets, Streams

  • Adding and retrieving members with scores (ZADD, ZRANGE, ZRANGEBYSCORE)

  • Sorted set operations (ZREM, ZINCRBY, ZREVRANGE)

  • Introduction to Streams (XADD, XREAD)

  • Caching strategies (cache-aside, write-through, write-behind)

  • Hands-on Exercise: Implementing a simple leaderboard with Sorted Sets

Day 3: Redis in Production & Advanced Topics

• Redis in Production

  • Session Management (basic implementation)

  • Rate Limiting (basic implementation)

  • Redis Persistence (RDB, AOF - high-level overview)

  • Introduction to Redis Clustering (Sentinel)

  • Hands-on Exercise: Implementing basic session management using Redis

• Best Practices & Troubleshooting

  • Performance optimization

  • Security considerations

  • Common Redis issues and troubleshooting techniques

  • Q&A and Wrap-up

Note:

• This 3-day outline focuses on the core concepts and essential applications of Redis.

• Hands-on exercises and real-world examples are crucial for effective learning and will be incorporated throughout the course.

• This course provides a solid foundation in Redis and its practical applications.
