tracker issue : CF-3040845

Problem:

CacheGetMetadata() Returns both Cache Wide and Item Specific MetadataCurrently, the cacheGetMetadata() function returns metadata that applies both to the individual cache item passed to the function as well as metadata for the entire cache region that the cached item came from.  For example, if you have an item in the cache with an ID of “item1” and you can get the metadata for it like this:<cfdump var="#cacheGetMetadata("item1")#">What this actually returns to you is a structure with two sets of information: Cache_hitcount and cache_misscount apply to the overall cache. In other words, how many hits and misses the entire cache have received.  The rest of the keys returned in the structure apply to the item passed in to the cacheGetMetadata() function.I see a couple of potential issues with how this has been implemented. What I think we really need is two separate functions here.  The existing cacheGetMetadata() should return just the metadata that is specific to the item passed to the function, not metadata on the entire cache.  I would expect a separate function to retrieve metadata for the cache itself.  To avoid confusion, I’d call the new function something like cacheGetStats().  In my mind it would return the cache_hitcount and cache_misscount that are currently returned by the cacheGetMetadata() function.  It would also return a whole lot more that’s available from ehcache but not exposed to ColdFusion – things like the total number of items currently in the cache, total size in bytes of all of the items in the cache, etc.
