How do you configure the default load balancing strategy in Dubbo?
The default load balancing strategy in Dubbo can be configured on the service provider side. You can add the following configuration options to the provider’s configuration file (dubbo.properties or dubbo.xml).
- Configuration item name: load balance.
- Configuration option value: the name of load balancing strategy, which can be one of the following:
random: randomly selects a service provider;
roundrobin: selects service providers in a round-robin manner, selecting them in the order they appear in the list;
leastactive: selects the service provider with the least active requests, i.e. the one with the fewest active requests;
consistenthash: uses consistent hashing to select a service provider based on a hash algorithm.
For example, the following configuration can be added to the dubbo.xml configuration file:
<dubbo:service interface="com.xxx.XxxService" loadbalance="random" />
The above configuration will set the load balancing strategy for the XxxService interface to randomly select a service provider.
