in fleet outputs settings if modifiying the hosts section and add multiple hosts will that mean that agent will send data the the second hosts only when the first one is unreachable , or data will be sent to the both nodes at the same time if yes could that lead to duplicated data in th cluster

We use the go-elasticsearch client to connect to nodes.
Data is not sent to all nodes for each request.
Connections will be distributed by round-robin to each host
See [Connecting | Elasticsearch Go Client [8.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/go-api/current/connecting.html#connecting-multiple-nodes) for more info.
