Load Balancer behaviour clarification

[pam2014]

The plugin provides load balancing across multiple elastic search nodes with round robin being the default behaviour. I have questions in it's behaviour in the following scenario

1. What happens if there is > 1 instance of fluentd with this plugin used to push data into elastic search?
2. Will each instance of gem work independently to load balance the data is receives?
3. If yes, it would mean that there is no true load balance because it is highly likely all the instances will be sending data to the same node at the same time
4. Is there any alternative such that likelihood of data from each instance lands in a different ES node?
5. The other two options of load balancing, how can the plugin be configured to use a different mode?
