Field Detail

SCRIPT_LOAD_BALANCER_PRECEDENCE

public static final int SCRIPT_LOAD_BALANCER_PRECEDENCE

The relative order of the ScriptLoadBalancer if one is enabled relative to other ClusterLoadBalancer instances that may be in the context. This allows users to fit 50 more balancer's between the script load balancer and the default RandomizedClusterLoadBalancerImpl. If the user wants to place a balancer implementation before the script one they only need to subtract from this value.
