QUAN currently does not show query-cache hitrate for specific query, though that would be useful feature.

How to repeat:

It also misses "I/O" information. while this is not directly available in MySQL internally there are various counters which pretty much proxy this type of information, even if they are on a per engine basis.

Making this information available to the proxy would be extremely useful.

Much of this information is hard to get at the moment but is a good fit for performance_schema support in the future.
Any current implementation would be too heavy-weight on the backend server on any somewhat server.
