Problems solved by technology

However, the existing balanced distribution method only considers the capacity of data slices. If the load of the moved data slice is too high, when it is moved to other servers, the load on other servers will be too large, which will still affect to the overall efficiency of the entire distributed database system

Abstract

The invention discloses a distributed database load leveling method, comprising: counting the load of all servers in the distributed database system and the load ratio of each data slice in each server; n servers are used as high-load servers, and the n servers with lower loads are used as low-load servers; the data slices with the highest load proportion among high-load servers are used as source data slices, and the load proportion of low-load servers is used as source data slices. The data slice that is sorted later is used as the target data slice, and the target data slice is swapped with the source data slice. The invention also discloses a distributed database load leveling device. The invention reduces the load in the high-load server, avoids the situation that the low-load server is overloaded due to the high-load server transferring data slices to the low-load server, and effectively reduces the load of the entire distributed database system.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for load balancing of distributed databases. Background technique [0002] In recent years, with the rapid growth of data volume, distributed database technology has also been developed rapidly. The distributed database divides the data in the original centralized database into a large number of data pieces, disperse and store them on multiple independent data storage nodes, and use the network to connect multiple physically dispersed data storage units to form a logically unified database. It adopts a scalable system structure and utilizes multiple servers to share the storage load, which not only improves the reliability, availability and access efficiency of the system, but is also easy to expand. In order to maintain a balanced distribution of data slices, when the distribution of the number of data slices on a server in the entire distributed datab...
