How Redis Caching Works — Animated Explainer | System Design #shorts

Redis caching explained with stunning animations! Learn how Redis sits between your app and database, how cache hits and misses work, and how TTL keeps your data fresh. I used this exact pattern at Mstock — a stock trading platform with 100K+ concurrent users — to turn 120ms lookups into 2ms.

⏱️ Timestamps:
0:00 — Your database is slow
0:03 — The problem: every request hits the DB
0:12 — Enter Redis: in-memory caching
0:25 — Cache HIT vs Cache MISS explained
0:40 — TTL: Time To Live (keeping data fresh)
0:52 — Real world: 60x faster at Mstock
0:57 — Follow for more
