APPARATUS AND METHOD FOR QUERY PRIORITIZATION IN A SHARED NOTHING DISTRIBUTED DATABASE
摘要
<p>A shared nothing distributed database system includes a master node and a set of shared nothing nodes. Each shared nothing node includes a node state table stored in memory that characterizes various statements and multiple processes implementing each statement, target resource consumption rate for each process and process activity information. A monitor module executed by a central processing unit processes information in the node state table and adjusts values in the node state table in accordance with priority criteria specifying individual user priority ascribed to a statement. A query associated with a statement is processed in the shared nothing distributed database system in accordance with the priority criteria.</p>
