Abstract

The invention relates to the technical field of data processing, in particular to a load balancing method and device. The method is applied to a load balancing system, and comprises: when it is detected that the number of cluster nodes changes, dividing the number of current task sets by the number of current nodes to obtain a quotient d and a remainder n; setting the number of bearable task sets of n first-class nodes with the maximum number of currently borne task sets as d+1, and setting the number of bearable task sets of second-class nodes except the first-class nodes as d; and adjusting the task set currently borne by each node, so that the number of the task sets currently borne by each node is equal to the number of the corresponding bearable task sets.

Description

technical field [0001] The present application relates to the technical field of data collection, and in particular to a load balancing method and device. Background technique [0002] In a cluster, task scheduling and dynamic load are unavoidable problems. In the operation and maintenance scenario, collection tasks not only need to achieve balanced task distribution and dynamic load, but also need to minimize the tasks of the same collection object Try to load to the same collector to reuse the collection connection, and the minimum task adjustment is required during dynamic load to ensure the continuity of the collection task and data continuity. [0003] Currently, a consistent hash algorithm is used to load to different nodes through hash. However, since the keys of the hash are all IP addresses, the hash degree of the hash is not high enough, and the distribution is not uniform enough. For example, the load hash value of a certain segment of IP addresses may be on the...
