Elasticsearch 8.x Cookbook - Fifth Edition

By: Alberto Paro

Overview of this book

Elasticsearch is a Lucene-based distributed search engine at the heart of the Elastic Stack that allows you to index and search unstructured content with petabytes of data. With this updated fifth edition, you'll cover comprehensive recipes relating to what's new in Elasticsearch 8.x and see how to create and run complex queries and analytics. The recipes will guide you through performing index mapping, aggregation, working with queries, and scripting using Elasticsearch. You'll focus on numerous solutions and quick techniques for performing both common and uncommon tasks such as deploying Elasticsearch nodes, using the ingest module, working with X-Pack, and creating different visualizations. As you advance, you'll learn how to manage various clusters, restore data, and install Kibana to monitor a cluster and extend it using a variety of plugins. Furthermore, you'll understand how to integrate your Java, Scala, Python, and big data applications such as Apache Spark and Pig with Elasticsearch and create efficient data applications powered by enhanced functionalities and custom plugins. By the end of this Elasticsearch cookbook, you'll have gained in-depth knowledge of implementing the Elasticsearch architecture and be able to manage, search, and store data efficiently and effectively using Elasticsearch.

Executing a snapshot

In the previous recipe, we defined a repository, that is, the place where we will store the backups. Now we can create snapshots of indices (using the full backup of an index) in the exact instant that the command is called.

For each repository, it's possible to define multiple snapshots.

Getting ready

You will need an up-and-running Elasticsearch installation – similar to the one that we described in the Downloading and installing Elasticsearch recipe of Chapter 1, Getting Started.

To execute the commands, any HTTP client can be used, such as Curl (https://curl.haxx.se/) or Postman (https://www.getpostman.com/). Additionally, you can use the Kibana console as it provides code completion and better character escaping for Elasticsearch.

To correctly execute the following commands, the repository that was created in the Managing repositories recipe is required.

To have a mybooks-1 index with a record, we will execute the following command...
