    摘要: According to one embodiment, a calculating device performs at least a calculation for a database system. A database of the database system is split into a plurality of partitions and placed in a plurality of nodes. The device is configured to accept statistical information relating to the plurality of partitions and the plurality of nodes and being collected by the plurality of nodes, and generate fluctuation information by using the statistical information and perturbation information. The perturbation information corresponds to statistical fluctuation of the statistical information. The device is configured to calculate a placement of the plurality of partitions in the plurality of nodes by using the statistical information and the fluctuation information. The placement is capable of improving a performance of the database system.
