Abstract
The disclosure discloses a method for adjusting distribution of partitioned data. Access frequency information of to-be-processed partitioned data is acquired when an adjustment time corresponding to the to-be-processed partitioned data has arrived; revenue data of each of data centers corresponding to the partitioned data is then determined according to the access frequency information and a preset revenue function; and finally, optimal distribution information is determined according to the revenue data of each of the data centers and a quantity of copies, and a position of each of the copies in each of the data centers is adjusted according to the optimal distribution information. Therefore, without even having to provide additional memory or hard disk for storage, this disclosure dynamically optimizes the distribution status of the partitioned data according to access frequencies and characteristics of the partitioned data, thus reducing transmission bandwidth requirements among data centers.
