    摘要: A method and system for providing query aware partitioning are disclosed. For example, the method receives a query plan comprising a plurality of queries, and classifies each one of the plurality of queries. The method computes an optimal partition set for each one of the plurality of queries, and reconciles the optimal partition set of each one of the plurality of queries with at least one subset of queries of the plurality of queries. The method selects at least one reconciled optimal partition set to be used by each query of the plurality of queries, and stores the selected at least one reconciled optimal partition set in a computer readable medium.
