Abstract
A method, an apparatus, and computer instructions are provided for a context based cache infrastructure to enable subset query over a cached object. Responsive to detecting a query to a root context of a context tree, the tree is traversed for a parent context of a subcontext corresponding to the name and value pair, which is identified by a user in the query. If the parent context caches all query results, the query results are iterated and the remaining name and value pairs are filtered out. However, if the parent context does not cache all query results, the traversing step is repeated for next parent context of the subcontext until a root context is encountered. If a root context is encountered, a query is issued to the database for the name and value pair and the result of the database query is cached in a new context.
