Most parallel database query processing methods proposed so far adopt the task-oriented approach: decomposing a query into tasks, allocating tasks to processors, and executing the tasks in parallel. However, this strategy may not be effective when some processors are overloaded with time-consuming tasks caused by some unpredictable factors such as data skew. In this paper, we propose a dynamic and load-balanced task-oriented database query processing approach that minimizes the completion time… CONTINUE READING
