- All Known Implementing Classes:
AbstractLoadBalancer
,RandomLB
,RoundRobinLB

public interface LoadBalancer
LoadBalancer
allows you to send operations to one of a number of endpoints (members). It is up to the implementation to use different load balancing policies.If the client is configured with
ClientNetworkConfig.isSmartRouting()
, operations that are not key-based will be routed to the endpoint returned by the LoadBalancer. For non-smart clients, theLoadBalancer
is not used.For configuration see
ClientConfig.setLoadBalancer(LoadBalancer)
.
