Dear all,  
I am using lumberjack output plugin to send logs from logstash to logstash. I use this code

```auto
       lumberjack {
               codec => json
               hosts => ["XXX","YYY"]
               port => ZZZ
               ssl_certificate => "/SERVICE/logstash/certs/PPPP/lumberjack.cert"
       }

```

We checked that lumberjack redirect the flow automatically to YYY when the server XXX is shut down and vice versa. However, I want to ask if the workload become very huge, does the lumberjack protocol do load balancing between the servers XXX et YYY.

Thanks in advance

My reading of the [code](https://github.com/elastic/ruby-lumberjack/blob/9df247e644eaf10fd634e00d255e09f2a4f7f7bf/lib/lumberjack/client.rb#L28) is that picks one of the list of hosts to connect to and sends everything to that. It does not balance across multiple connections.
