Could you explain more ? :smiley: For convenience, this pr add something like `public Builder putServerProperty(String key, String value) ` in each configurations like `serverProperties`, `consumerProperties`. So we don't need to do deep copy in ClusterConfig.Builder. Or did you mean we need to use `setServerProperty(Map<String, String> serverProperties)` instead of `putServerProperty(String key, String value)` ? -- This is an automated message from the Apache Git Service.
