An example of an AI chatbot conversation about Redis TTL commands and their usage.
What are Redis TTL commands and how do I use them?
Redis TTL (Time To Live) commands allow you to set an expiration time on keys. You can use commands like EXPIRE, PEXPIRE, and SETEX.
Can you explain how the EXPIRE command works?
Sure! The EXPIRE command sets a timeout on a key. After the specified number of seconds, the key will be automatically deleted.
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.
Are there any other commands related to TTL?
Yes, besides EXPIRE, you can use PEXPIRE for milliseconds, and TTL to check the remaining time before expiration.
