# Redis 101

**[Ido Shamun](https://daily.dev/sources/28849d86070e4c099c877ab6837c61f0)** · [@idoshamun](https://daily.dev/idoshamun) · 68 upvotes · 1 comments

## Summary

Redis is an in-memory data structure store that achieves exceptional speed through three key factors: storing data in RAM instead of disk, single-threaded command execution to avoid multithreading overhead, and highly optimized C code with custom data structures. It uses an event-driven architecture with I/O multiplexing to handle thousands of concurrent connections efficiently. Redis provides two persistence mechanisms (RDB snapshots and AOF logs) to ensure data durability despite being RAM-based. Common use cases include caching frequently accessed data like user profiles and serving as a primary database for real-time applications like gaming leaderboards using sorted sets.
