An example of an AI chatbot conversation about Redis TTL and EXPIRE commands.
What is the difference between TTL and EXPIRE in Redis?
In Redis, TTL (Time To Live) is a command that returns the remaining time to live of a key, while EXPIRE sets a timeout on a key.
Can you give me an example of how to use EXPIRE?
Sure! You can use the EXPIRE command like this: EXPIRE mykey 300 which sets a timeout of 300 seconds for 'mykey'.
What happens when the TTL expires?
When the TTL expires, the key is automatically deleted from the database.
Is there a way to check if a key has an expiration set?
Yes, you can use the TTL command to check if a key has an expiration set. It will return the remaining time or -1 if it doesn't.
