F1 Redis — Crash Course to Advanced Patterns

From basic caching to distributed rate limiting, Top-K, and leaderboards

Redis fundamentals and advanced patterns for system design interviews. Cover data structures (strings, hashes, sorted sets, HyperLogLog, streams), persistence modes (RDB/AOF), replication and Redis Cluster, then dive into advanced use cases: distributed rate limiting (token bucket via Lua scripts), real-time Top-K (sorted sets + probabilistic structures), leaderboards, session stores, and pub/sub.
