How does Redis expiration work in Rails caching?

How does Redis expiration work in Rails caching?

Redis expiration allows you to set a time-to-live (TTL) for cached items in Rails, automatically removing them after a specified duration.

Can I set different expiration times for different cache keys?

Yes, you can set different expiration times for each cache key by specifying the TTL when you store the item in Redis.

What happens if I don't set an expiration time?

If you don't set an expiration time, the cached item will remain in Redis until it is manually deleted or the memory limit is reached.

How can I check the remaining time for a cached item?

You can use the TTL command in Redis to check the remaining time for a cached item. It returns the time in seconds.
