Redis · from first command to FAANG-level design
Stop saying "just use Redis".
Know which primitive, why, and what breaks.
Redis taught as data structures, atomicity, caching, persistence, replication, clustering and failure handling, not as a list of commands. Every topic works through a real interview problem and the ways it breaks in production: leaderboards, rate limiters, distributed locks, idempotency, streams, cache stampedes, hot keys, Sentinel and Cluster failover, multi-region, security, observability, vector search, and Spring Boot integration, ending with staff-level designs, a capstone, and a full interview question bank.

By the end you can
What this course makes you able to do
- Pick the right Redis structure for a problem and explain its complexity, memory cost, and atomicity
- Build caches, rate limiters, counters, leaderboards, queues, and sessions that stay correct under concurrency
- Use
MULTI/WATCH, Lua, Functions, and pipelining correctly, and know which one each problem needs - Design locks with fencing tokens, idempotency keys, deduplication, and delayed-job schedulers, and explain where Redis alone isn't safe
- Run Redis in production: persistence, replication, Sentinel, Cluster, security, monitoring, and latency debugging
- Answer staff-level Redis design questions with the full reasoning chain: requirement → primitive → atomicity → failure → scale → trade-offs

Where should I start?
Pick a path for your goal
Backend developer (0–2 years)
You use Redis as "the cache" and want to use it properly.
- 10 · Redis Foundations
- 21 · Core Data Structures
- 32 · Expiration, Eviction & Memory
- 43 · Atomicity: Transactions, Lua, Functions & Pipelining
- 56 · Caching Patterns
- 67 · Rate Limiting & Distributed Counters
Then Phase 8 to integrate it cleanly into your app.
Interview-ready (2–4 years)
You need to design caches, queues, locks, and rate limiters in interviews.
- 13 · Atomicity: Transactions, Lua, Functions & Pipelining
- 25 · Messaging: Pub/Sub, Streams & Notifications
- 36 · Caching Patterns
- 49 · Persistence & Durability
- 510 · Replication & High Availability
- 611 · Redis Cluster
- 712 · Distributed Coordination
Finish with the Phase 16 question bank.
Senior / Staff
You own Redis in production or lead system design rounds.
