What is the Redis TTL command and how do I use it?
The Redis TTL command is used to get the time-to-live of a key. It returns the remaining time in seconds before the key expires.
How do I set a TTL for a key in Redis?
You can set a TTL using the EXPIRE command. For example, EXPIRE mykey 300 sets a TTL of 300 seconds.
What happens when the TTL expires?
When the TTL expires, the key is automatically deleted from the database.
Can I check the TTL of a key that doesn't exist?
Yes, if the key does not exist, the TTL command will return -2, indicating that the key does not exist.
