About Redis, covering many aspects, from basic concepts to advanced applications, and best practices. For example the following:

1. Meet Redis:

   • What is Redis? What are its features and advantages?
   • Redis data structures: strings, hashes, lists, sets, sorted sets, bitmaps, etc.

2. Install and configure Redis:

   • Install Redis on different operating systems.
   • Configure basic settings and security parameters for Redis.

3. Basic operation:

   • How to connect to Redis server.
   • Set and get key-value pairs.
   • Manage data with expiration and TTL.
   • Batch operations and atomic operations.

4. Data structures and applications:

   • String: purpose, action, and example.
   • Hash: purpose, operation, and examples.
   • List: purpose, operation and examples.
   • Sets and Sorted Sets: Purpose, Operations, and Examples.
   • Bitmaps: Uses, Operations, and Examples.

5. Publish and subscribe mode:

   • What is the publish-subscribe pattern?
   • How to implement real-time message communication using the publish-subscribe pattern.

6. Persistence and snapshots:

   • RDB Snapshots: How to do periodic snapshot backups and restores.
   • AOF log: How to do persistent logging.

7. Advanced features:

   • Transactions: How to use transactions to keep multiple operations atomic.
   • Lua scripts: Execute Lua scripts in Redis.
   • A comparison of Lua scripts and transactions.

8. Clusters and shards:

   • Redis Cluster: Data sharding in a distributed environment.
   • Master-slave replication and Sentinel.

9. Performance Optimization and Best Practices:

   • Use connection pools and pipes to improve performance.
   • Memory optimization and eviction strategies.
   • Cache design and solutions for cache breakdown, avalanche, and penetration.

10. Integration with other technologies:

    • Redis integrates with Spring Boot.
    • Application of Redis in microservice architecture.
    • The combination of Redis and message queue.

11. Case studies and application examples:

    • Build session management and user authentication with Redis.
    • Build real-time leaderboards and counters.
    • Use Redis to implement distributed locks.

12. Security and Operations:

    • How to protect Redis data security.
    • Redis High Availability and Failure Recovery Strategies.

13. Common problem solving:

    • How to solve the problem of high memory usage of Redis.
    • How to deal with Redis master-slave synchronization delay, etc.

Regardless of beginners or experienced developers, after mastering these contents, they will have a better understanding and application of Redis.
