> The LRUCache used for query result caches expose the following stats:
> # maxRamMB
> # ramBytesUsed
> # evictionsRamUsage
> The last one is not relevant to FastLRUCache as its behavior is to either evict by size
or by heap but not both. However, the first two should be exposed by FastLRUCache as well.
