/**
 * A result is saved in multiple cache keys, there is the originally specified
 * cache key which is just pointing to result rows by key. The following things
 * have to be ensured:
 *
 * 1. lifetime of the original key has to be longer than that of all the individual rows keys
 * 2. if any one row key is missing the query has to be re-executed.
 *
 * Also you have to realize that the cache will load the whole result into memory at once to ensure 2.
 * This means that the memory usage for cached results might increase by using this feature.
 *
 * @internal The class is internal to the caching layer implementation.
