- Each node is assigned a role (or multiple roles) that defines its responsibilities within the cluster.
- Nodes work together to distribute data and operations across the cluster and ensuring high availability and performance.
How to Configure all Elasticsearch Node Roles?
Elasticsearch is a powerful distributed search and analytics engine that is designed to handle a variety of tasks such as full-text search, structured search, and analytics. To optimize performance and ensure reliability, Elasticsearch uses a cluster of nodes, each configured to handle specific roles.
Understanding and properly configuring these node roles is essential for managing Elasticsearch effectively. In this article, we will go through the What is Nodes, different types of Nodes their roles in an Elasticsearch cluster.
