ABSTRACT:
Query results are pre-cached for a substantial portion of or all queries that are likely to be issued by users. One query can be entirely different from another query, yet because corresponding query results are pre-cached, the database need not be accessed, improving response performance. Pre-cached queries are also distributed into multiple partitions to apportion work among multiple computing machines to further enhance performance and provide redundancy in case of the failure of any particular partition. Pre-cached query results are selectively refreshed so that users may enjoy up-to-date information by focusing on queries that are popular as well as queries that are old.
