-Cluster cluster.name = elasticsearch -Nodes: -Allow this node to be eligible as a master node (enabled by default): #node.master: true -Allow this node to store data (enabled by default): #node.data: true

You can exploit these settings to design advanced cluster topologies. Node example: 1. You want this node to never become a master node, only to hold data. This will be the "workhorse" of your cluster. node.master: false node.data: true

Slide 10

Slide 10 text

Node example: 2. You want this node to only serve as a master: to not store any data and to have free resources. This will be the "coordinator" of your cluster. node.master: true node.data: false

Slide 11

Slide 11 text

Node example: 3. You want this node to be neither master nor data node, but to act as a "search load balancer" (fetching data from nodes,aggregating results, etc.) node.master: false node.data: false
