Elasticsearch 7.0 Cookbook - Fourth Edition

By: Alberto Paro

Overview of this book

Elasticsearch is a Lucene-based distributed search server that allows users to index and search unstructured content with petabytes of data. With this book, you'll be guided through comprehensive recipes on what's new in Elasticsearch 7, and see how to create and run complex queries and analytics. Packed with recipes on performing index mapping, aggregation, and scripting using Elasticsearch, this fourth edition of Elasticsearch Cookbook will get you acquainted with numerous solutions and quick techniques for performing both every day and uncommon tasks such as deploying Elasticsearch nodes, integrating other tools to Elasticsearch, and creating different visualizations. You will install Kibana to monitor a cluster and also extend it using a variety of plugins. Finally, you will 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 book, you will have gained in-depth knowledge of implementing Elasticsearch architecture, and you'll be able to manage, search, and store data efficiently and effectively using Elasticsearch.

Setting up an NFS share for backups

Managing the repository (where the data is stored) is the most crucial part in Elasticsearch backup management. Due to its native distributed architecture, the snapshot and the restore are designed in a cluster style.

During a snapshot, the shards are copied to the defined repository. If this repository is local to the nodes, then the backup data is spread across all the nodes. For this reason, it's necessary to have shared repository storage if you have a multinode cluster.

A common approach is to use an NFS, as it's very easy to set up and it's a very quick solution (additionally, standard Windows Samba shares can be used.)
