Can you explain what the TTL term means in the context of caching?

TTL (Time To Live) in caching context is the lifetime of a cached object. It determines how long data will be stored in cache before it becomes outdated and is removed or refreshed. For example, if TTL is set to 60 seconds, after this time the cache will automatically reset, and the next request will fetch data anew from the primary source.

This helps control data relevance and prevents using stale information.
