Most frequently evicted keys

1 votes

It would be useful to know which keys are not being used, that is those that are being set and not accessed (or infrequently accessed). I have no idea if this data is attainable but just an idea!

This is an interesting suggestion. We currently do not get this data from our servers but this would be solvable. The problem I see however is that getting "most frequently evicted items" would require us to get stats about keys on a timescale that cannot be reasonably done (needs more resources than to operate the cache).

Could you achieve what you want by the following?
1. Look at the most set keys.
2. Watch prefixes that have a drastically lower than overall hit rate.
