Class QueryCacheEntry


public class QueryCacheEntry extends Object
For query cache entries we additionally hold the dependent tables and timestamp for the query result.

We use the dependent tables and timestamp to validate that tables the query joins to have not been modified since the query cache entry was cached. If any dependent tables have since been modified the query cache entry is treated as invalid.
