Create a follower index to replicate a specific index

ECE ECK Elastic Cloud Hosted Self Managed

When you create a follower index, you reference the remote cluster and the leader index in your remote cluster.

To create a follower index from Stack Management in Kibana:

  1. Select Cross-Cluster Replication in the side navigation and choose the Follower Indices tab.
  2. Choose the cluster (ClusterA) containing the leader index you want to replicate.
  3. Enter the name of the leader index, which is kibana_sample_data_ecommerce if you are following the tutorial.
  4. Enter a name for your follower index, such as follower-kibana-sample-data.

Elasticsearch initializes the follower using the remote recovery process, which transfers the existing Lucene segment files from the leader index to the follower index. The index status changes to Paused. When the remote recovery process is complete, the index following begins and the status changes to Active.

When you index documents into your leader index, Elasticsearch replicates the documents in the follower index.
