    • Embodiments of the invention provide techniques for aggregating database queries for energy efficiency. In one embodiment, queries received by a DBMS are aggregated and staged according to hard-disk drives required for query execution. Each group of queries accessing a given drive may be dispatched for execution together. Further, the queries received by a DBMS may be matched to patterns of previously received queries. The matching patterns may be used to predict other queries which are likely to be received by the DBMS. The received queries may be staged to be dispatched with the predicted queries. By aggregating queries to be executed, access to each hard-disk drive may be optimized, thus reducing the overall energy consumption required for executing the queries.
    • 本发明的实施例提供了用于聚合用于能量效率的数据库查询的技术。 在一个实施例中,由DBMS接收的查询根据查询执行所需的硬盘驱动器进行聚合和分段。 可以一起调度访问给定驱动器的每组查询。 此外,由DBMS接收的查询可以与之前接收到的查询的模式相匹配。 匹配模式可用于预测DBMS可能接收到的其他查询。 所接收的查询可以被分段以用预测的查询进行调度。 通过聚合要执行的查询,可以优化对每个硬盘驱动器的访问,从而降低执行查询所需的总体能量消耗。
