There's no way to retrieve the metadata back from an item aside from the client flags as part of a normal command.
What people typically do is embed the original TTL into the object you've stored. that way the application can read it or any other metadata you want to make decisions with. Though I see you said "by hand" - are you debugging something or designing a flow in your app to remove stale data? If you're debugging, "lru_crawler metadump" will get you the data, but you need a newer version I think. On Fri, 22 Mar 2019, Daniel Ellis wrote: > As far as I know, cachedump is the only way.
