类 GreedyPriorityBalancer

java.lang.Object

org.apache.iotdb.confignode.manager.load.balancer.router.priority.GreedyPriorityBalancer

所有已实现的接口:

IPriorityBalancer

直接已知子类:

LeaderPriorityBalancer

public class GreedyPriorityBalancer
extends java.lang.Object
implements IPriorityBalancer

The GreedyPriorityBalancer always pick the Replica with the lowest loadScore

从接口复制的说明: IPriorityBalancer

Generate an optimal route priority.

指定者:

generateOptimalRoutePriority 在接口中 IPriorityBalancer

参数:

replicaSets - All RegionGroups

regionLeaderMap - The current leader of each RegionGroup

dataNodeLoadScoreMap - The current load score of each DataNode

返回:

Map, The optimal route priority for each RegionGroup. The replica with higher sorting result have higher priority.
