Master Redis EXPIRE and TTL Secrets
Redis key expiration is one of the most powerful features for caching, session handling, and performance optimization — but most beginners use it wrong.
In this video, you’ll learn exactly how EXPIRE, PEXPIRE, TTL, and automatic deletion work in Redis, with simple hands-on examples.
You’ll see how to:
• Check if a key has expiration
• Add expiration to an existing key
• Create a key that expires automatically
• Verify whether the key still exists with EXISTS
• Watch a key “disappear” in real time
Perfect for backend devs, Node.js engineers, Go/Python developers, and anyone using Redis as a cache or session store.
