Elasticsearch Cluster Operation Example detailed

Rest interface Now that we have a functioning node (and cluster), the next step is to understand how to communicate with it. Fortunately, Elasticsearch provides a very comprehensive and powerful rest API that allows you to interact with your cluster using this REST API. Here are a few things you can do with this API: 1, check your cluster, node and index health status and various statistical information2. Manage your clusters, nodes, index data, and

Elasticsearch Learning Java Operations 1

1. Elasticsearch provides two built-in client 1.1 node clients for Java users: The node client joins the cluster with no data node (none), in other words, it does not store any data itself. But it knows exactly where the data is in the cluster and is able to forward requests directly to the corresponding nodes. Transport clients (Transport client): This lighter-weight transport client is able to send requests to a remote cluster. It does not join t
