ElasticSearch is natively designed for the Cloud, so when you need to release a production environment with a huge number of records, and you need high availability and good performances, you need to aggregate more nodes in a cluster.
ElasticSearch allows you to define different type of node to balance and improve overall performance.
For the advanced setup of a cluster, there are some parameters that must be configured to define different node types.
These parameters are in config/elasticsearch.yml
and can be set by performing these steps:
Set up whether or not the node can be a master node:
node.master: true
Set up whether or not a node must contain data:
node.data: true
