<div class="block">Different from a simple exact mapping from keys to values,
it leverages the fact that the results of a Subquery A with limit X are first X entries of the results of the
a Subquery B with limit Y, where A and B only differ in limit, and X is less than or equal to Y.
<p>
For example, suppose the cache is empty at the beginning. Firstly, prop1_idx:multiKSQ[1]@100 query leads to a cache
miss, and then results are loaded into cache. Secondly, prop1_idx:multiKSQ[1]@20 query leads to a cache hit, and
then first 20 results of cached responses are returned. Thirdly, prop1_idx:multiKSQ[1]@2000 leads to a cache miss,
then results are loaded into cache, and initial results saved by prop1_idx:multiKSQ[1]@100 query are overriden by
the new results.
<p>
Internally, raw query results are encapsulated in <code>SubqueryResult</code> object together with limit of the query.
Meanwhile, keys are stored without limit (or with a dummy limit). Whenever there is a hit for key, the limit of
cached results and that of the query will be compared, and whether this is a cache hit or miss will be determined.
<p>
Compared to a simply <code>JointIndexQuery.Subquery</code> to <code>List<Object></code> mapping, this cache has two benefits:
1) it reduces latency, as "subset" queries can effectively leverage cached results.
2) it saves space, as queries only differing in limit will not be saved more than once in cache.</div>
