Examples of org.apache.helix.controller.rebalancer.config.RebalancerConfig

org.apache.helix.controller.rebalancer.config.RebalancerConfig
Defines the state available to a rebalancer. This is fully optional, but it allows persistence of arbitrary fields that would be useful for a user-defined rebalancer

    ResourceConfiguration configuration = new ResourceConfiguration(resourceId);
    if (resource.getUserConfig() != null) {
      configuration.addNamespacedConfig(resource.getUserConfig());
      persistConfig = true;
    }
    RebalancerConfig rebalancerConfig = resource.getRebalancerConfig();
    if (rebalancerConfig != null) {
      // only persist if this is not easily convertible to an ideal state
      configuration.addNamespacedConfig(new RebalancerConfigHolder(rebalancerConfig)
          .toNamespacedConfig());
      persistConfig = true;
