Setting up different node types

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 defining different type of nodes to balance and improve overall performances.

Getting ready

You need a working Elasticsearch installation as we described in the Downloading and installing Elasticsearch recipe and a simple text editor to change the configuration files.

How to do it...

For advance, set up a cluster. There are some parameters that must be configured to define different node types.

These parameters are in config/elasticsearch.yml file and they can be set with the following steps:

1. Set up whether the node can be master or not:

           node.master: true 
   

2. Set up whether a node must contain data or not:

           node.data: true 
   

How it works...

The node.master parameter defines that the node can become master...
