1. An apparatus comprising: at least one processor; a memory coupled to the at least one processor; a plurality of queries to a database; and a query governor that performs the steps of: determining a first of the plurality of queries cannot be executed in less time than a specified threshold value; in response to determining the first query cannot be executed in less time than the specified threshold value, performing the steps of: executing an access plan for the first query for a period of time less than the specified threshold value; halting execution of the access plan; and returning the partial results for the first query; determining a second of the plurality of queries cannot be executed in less time than the specified threshold value; in response to determining the second query cannot be executed in less time than the specified threshold value, performing the steps of: executing a first access plan for the second query for a first period of time; executing a second access plan for the second query for a second period of time, wherein the first period of time added to the second period of time is less than the specified threshold value; and returning query results from executing the first access plan and the second access plan as the partial results for the second query; determining a third of the plurality of queries cannot be executed in less time than the specified threshold value; in response to determining the third query cannot be executed in less time than the specified threshold value, performing the steps of: simultaneously executing first and second access plans for the third query; and returning results of executing the first and second access plans as the partial results for the third query; determining a fourth of the plurality of queries cannot be executed in less time than the specified threshold value; in response to determining the fourth query cannot be executed in less time than the specified threshold value, performing the steps of: modifying the fourth query to omit at least one portion of the fourth query; executing the modified fourth query; and returning results of executing the modified fourth query as the partial results for the query.
