An example of an AI chatbot conversation about Redis key expiration and its functionality.
What is Redis key expiration and how does it work?
Redis key expiration allows you to set a time-to-live (TTL) for keys, after which they are automatically deleted.
How do I set an expiration time for a key in Redis?
You can use the EXPIRE command followed by the key and the number of seconds until expiration.
Can I check the remaining time before a key expires?
Yes, you can use the TTL command to check the remaining time in seconds for a key.
What happens if I try to access a key after it has expired?
If you try to access a key after it has expired, Redis will return a nil value, indicating that the key no longer exists.
