From the documentation it’s not completely clear to me how GL->ES connection should be configured.
For example I have 3 ES nodes.
Is it enough to configure
elasticsearch_hosts = any_es_master_node
(Because master will handle all messages forwarding to other nodes. And in case of adding new ES node I will not have to restart GL)
Or it’s mandatory to configure all-to-all connections
@zoulja To avoid issues with the connection to the Elasticsearch cluster, you should add some of the network addresses of the Elasticsearch nodes to elasticsearch_hosts.
And it’s mandatory to configure all-to-all connections by specifying “elasticsearch_hosts.”
