Elasticsearch Essentials

Overview of this book

With constantly evolving and growing datasets, organizations have the need to find actionable insights for their business. ElasticSearch, which is the world's most advanced search and analytics engine, brings the ability to make massive amounts of data usable in a matter of milliseconds. It not only gives you the power to build blazing fast search solutions over a massive amount of data, but can also serve as a NoSQL data store. This guide will take you on a tour to become a competent developer quickly with a solid knowledge level and understanding of the ElasticSearch core concepts. Starting from the beginning, this book will cover these core concepts, setting up ElasticSearch and various plugins, working with analyzers, and creating mappings. This book provides complete coverage of working with ElasticSearch using Python and performing CRUD operations and aggregation-based analytics, handling document relationships in the NoSQL world, working with geospatial data, and taking data backups. Finally, we’ll show you how to set up and scale ElasticSearch clusters in production environments as well as providing some best practices.

Summary


In this chapter, you learned how to create data backups of an Elasticsearch cluster and restore them back into the same or another cluster. You also learned how to secure Elasticsearch clusters and load balance them using Nginx.

Finally, we have reached the end of the book, and we hope that you have had a pleasant reading experience. Elasticsearch is vast, and covering every tiny detail in this book was not possible. However, as per the goal, it covers almost every "essential" topic of Elasticsearch for developers to start from scratch and to be able to manage and scale an Elasticsearch cluster on their own. Most interestingly, this book serves both Java and Python programmers under one hood.

Not only has Elasticsearch matured, but the community around this technology is also much more mature now. If you face any issue, you can post your questions to the official user discussion group: https://discuss.elastic.co.
