Abstract
An improved system for database query processing by means of 'query decomposition' intercepts database queries prior to processing by a database management system ('DBMS'). The system decomposes at least selected queries to generate multiple subqueries for application, in parallel, to the DBMS, in lieu of the intercepted query. Responses by the DBMS to the subqueries are assembled by the system to generate a final response. The system also provides improved methods and apparatus for storage and retrieval of records from a database utilizing the DBMS's cluster storage and index retrieval facilitates, in combination with a smaller-than-usual hash bucket size.
