Remote Clusters

Use Remote Clusters to establish a unidirectional connection from your cluster to other clusters. This functionality is required for cross-cluster replication and cross-cluster search.

To get started, go to Management > Remote Clusters.

A remote cluster connection works by configuring a remote cluster and connecting to a limited number of nodes, called seed nodes, in that cluster. Alternatively, you can define a single proxy address for the remote cluster.

By default, a cross-cluster request, such as a cross-cluster search or replication request, fails if any cluster in the request is unavailable. To skip a cluster when its unavailable, set Skip if unavailable to true.

Once you add a remote cluster, you can configure cross-cluster replication to reproduce indices in the remote cluster on a local cluster.

To create an index pattern to search across clusters, use the same syntax that you’d use in a raw cross-cluster search request in Elasticsearch: <cluster-names>:<pattern>. See Creating an index pattern for examples.

From the Remote Clusters list view, you can drill down into each cluster and view its status. You can also edit and delete a cluster.
