Spring Cloud Ribbon Client load Balancing policy

Load Balancing Policy

Abstractloadbalancerrule

An abstract class of load balancing policies that defines a load Balancer Iloadbalancer object that can be obtained when a service policy is selected for a specific implementation

Some of the information maintained in load balancing as a basis for allocation and design algorithms to implement efficient strategies for specific scenarios

Randomrule

Randomly select a service instance

Roundrobinrule

How to poll linearly

Retryrule

Implements an instance selection function with retry mechanism

Weightedresponsetimerule

This strategy is an extension of the roundrobinrule, which increases the calculation of weights based on the operation of the instance, and selects instances based on weights to achieve better allocation results.

Scheduled Tasks

Serverweighttimer.schedule (New Dynamicserverweighttask (), 0, Serverweighttasktimerinterval); Start a scheduled task,

Used to calculate weights for each service instance
