Design and implementation of Dubbo adaptive load balancing with priority random load
Dubbo-based stochastic load balancing
The random strategy will first determine whether all Invokers have the same weight.
If they are the same, then the process is relatively simple. Using random. nexInt (length) you can randomly generate an Invoker serial number
Select the corresponding Invoker according to the serial number. If no weight is set on the service provider, then all Invoker weights are the same, default is 100.
If the weights are different, then we need to combine the weights to set the random probability.
Random Load Balancing after Modification
Get the address of a service from the locally currently registered provider service, and if it is the same as the IP of the current machine, get the provider first.
If different, re-load the random load and retrieve a provider service
