Redis interview questions, quiz and handbook in your Learning Dashboard
What you will learn
- Cache-aside with TTLs is the default caching pattern.
- SET with NX and an expiry gives a simple lock.
- INCR with EXPIRE implements fixed-window rate limits.
More than a cache
Redis is an in-memory data store with rich data structures: strings, hashes, lists, sets, sorted sets and streams. That makes it useful far beyond caching: sessions, leaderboards, queues, locks and rate limits.
Its speed comes from memory and simple operations, so the design question is always what happens when Redis is unavailable or the data is lost.
