This is a "nice to have" which probably will not appear until I redo the cache code to allow multi-threaded and multi-process caches. Currently the effect would be to take a write lock in each process whenever the cache needs feeding. This would then cause retries to stack up the processes on the database.

My target architecture is to have a tiered cache with a shared central cache that is fed from the database(s), Once this is implemented I can introduce a statistics section in the cache which can record both record lookups and also database fetches.

I would be inclined to save this on a lazy update cycle, so that it does not introduce real time updates into the query path - so requires som e careful thought.
