A node is a single instance of the Elasticsearch server and it can host data. This means that shards of indices are allowed to be allocated on the nodes. By default, each node is considered to be a data node, but you can turn the setting off.
There are two types of non-data nodes: dedicated master nodes and client nodes.
Another type of Elasticsearch node is tribe node. Normally, a node is associated with a single cluster. But sometimes, all the connected clusters may feel the need to get information. In other words, you may want to access data from multiple clusters. The tribe nodes respond to this need. A tribe node acts as a federated client across multiple clusters. The tribe
node works to retrieve the state of all connected clusters and merges them into a global cluster state:
tribe: appellation1: cluster.name: cluster_user appellation2: cluster.name: cluster_employee
When configuring a tribe node, it just needs to list the clusters that should be joined. The appellation1
and appellation2
are arbitrary names representing the connection to each cluster.
