If one node fail, could another one succeed to receive data?

Hi everyone, this is my cluster structure:

I use node1 to receive data from logstash.
But I am worry about that if node1 failed, could node2 or node3 succeed to node1 to receive the data from logstash, otherwise all the system would crash.

thank you in advance!

You can specify multiple nodes in the Logstash Elasticsearch output plugin, which will allow Logstash to send data to any of the specified nodes.


ok, I know that, but the mechanism is that duplicate data into many nodes at the same time.(is it?
or is it distribution concept?

Each request will go to one of the nodes in the cluster. If a request fails it will be retried against another node.
