2results about How to "Uniform data" patented technology

The application discloses a data balancing method and device, equipment and storage medium, and relates to the technical field of computers. The method comprises the following steps: performing hash processing on first samples and second samples in a data set, and mapping the first samples and the second samples into first hash buckets and second hash buckets; determining second samples matched with the first samples in the first hash buckets from second hash buckets adjacent to first hash buckets in the first hash buckets; searching in adjacent hash buckets in a counterfactual search process, reducing a search range, reducing a search amount, and improving search efficiency. Then, based on a feature relationship between the first samples and the second samples, third samples in the second samples are processed to obtain fourth samples. The labels of the fourth samples are consistent with the labels of the first samples, and data balancing is realized. Since the time required by the search process is shortened, the efficiency of data balancing is improved.

This application provides a data scheduling method, a distributed storage system, a computing device, a storage medium, and a computer program product. The data scheduling method includes: responding to a data scheduling request, determining at least one data item to be scheduled for a target object; determining weight coefficients corresponding to each of the plurality of racks; the initial value of the weight coefficients is determined based on the number of data nodes deployed in the racks; determining at least one target rack to allocate the at least one data item to based on the weight coefficients corresponding to the plurality of racks; and attenuating the weight coefficients corresponding to the at least one target rack based on the number of data items to be scheduled for the target object allocated to each of the at least one target racks. The technical solution provided by this application improves the availability of storage services in a distributed storage system.
