Title: METHOD AND DEVICE FOR LEVELING LOAD OF DISTRIBUTED DATABASE
Abstract:
Disclosed is a method for leveling the load of a distributed database. The method comprises: carrying out statistics on loading capacities of all servers in a distributed database system and load proportions of all data slices in all the servers; sorting the loading capacities, the top n servers being taken as high-load servers, and the last n servers being taken as low-load servers; sorting the load proportions of the high-load servers, the top ranking data slices being taken as source data slices, and sorting the load proportions of the low-load servers, the last ranking data slices being taken as target data slices; and exchanging the target data slices and the source data slices. Also disclosed is a device for leveling the load of a distributed database.
