Overview of this book

Elasticsearch is one of the most popular tools for distributed search and analytics. This Elasticsearch book highlights the latest features of Elasticsearch 7 and helps you understand how you can use them to build your own search applications with ease. Starting with an introduction to the Elastic Stack, this book will help you quickly get up to speed with using Elasticsearch. You'll learn how to install, configure, manage, secure, and deploy Elasticsearch clusters, as well as how to use your deployment to develop powerful search and analytics solutions. As you progress, you'll also understand how to troubleshoot any issues that you may encounter along the way. Finally, the book will help you explore the inner workings of Elasticsearch and gain insights into queries, analyzers, mappings, and aggregations as you learn to work with search results.

The best cluster configuration approaches

The best configuration approaches vary depending on the hardware you are using. The Elasticsearch cluster is a group of connected nodes, and its power relies on the distribution of tasks across these nodes. There are four types of node:

  • Data nodes, which store and handle data
  • Master nodes, which manage and configure cluster-wide actions
  • Client nodes, which send requests to data or master nodes, according to the type of request
  • Ingest nodes, which preprocess documents before indexing

As we saw in the previous sections, a node is automatically indexed and has a unique identifier. There are two types of cluster configuration for Elasticsearch: cloud and on-site configuration.
