Cache per item usage meta data?

[javafanboy]

As Coherence can perform eviction based on usage frequency and most recently accessed this information must ad I understand it be stored somewhere... is this information today readable in some way through an API (when I asked a similar question some years ago I interpreted the answer as no such info was available and never perused it further at that time).

Now the need has surfaced again. Even if I get the backing map (something I have used for some other custom stuff) I have not seen a way to get these statistics :-(

I think it would be valuable to be able to get this information without yourself having to duplicate it in the application...

After diving into the source I think I have found that the statistics are held in LocalCache.Entry that I can get through the backing map that requires a deprecated method to access ..

In this application we are currently not using Caffeine based Cache but as discussed before I am aware it do provide operations to get an approximation of the N best (or worst) keys that I can get hold of by accessing the backing map so that is another option but this requires a bit more work as we need to see that it works at least as good for our access pattern...
