  • Query optimization with awareness of limited resource usage
    Patent number: 8712972
    Abstract: System, method, computer program product embodiments and combinations and sub-combinations thereof for tuning query execution performance in a database management system are described. In an aspect, query optimization in a database management system (DBMS) with awareness of limited resource usage includes identifying limited resource usage for each possible plan being considered for query execution by a query engine. A determination of whether any possible plan has limited resource usage that does not exceed a threshold level is made, and when at least one possible plan does not exceed the threshold level, the identified limited resource usage is included as a consideration during plan selection by the query engine. In an embodiment, temporary database usage is identified for each possible plan.
