I was just reading this article: https://www.elastic.co/guide/en/logstash/current/deploying-and-scaling.html
I'm wondering how writing to multiple Elasticsearch nodes works in Logstash. In particular, let's assume I am shipping log events out of an single Logstash instance to 3 ELS Nodes. Like shown in the images here:
What happens, if one of those ELS nodes becomes unavailable? Is logstash trying it again on the same node or does it "hand over" the event to the next available node?
