Overview of this book

Building enterprise-grade distributed applications and executing systematic search operations call for a strong understanding of Elasticsearch and expertise in using its core APIs and latest features. This book will help you master the advanced functionalities of Elasticsearch and understand how you can develop a sophisticated, real-time search engine confidently. In addition to this, you'll also learn to run machine learning jobs in Elasticsearch to speed up routine tasks. You'll get started by learning to use Elasticsearch features on Hadoop and Spark and make search results faster, thereby improving the speed of query results and enhancing the customer experience. You'll then get up to speed with performing analytics by building a metrics pipeline, defining queries, and using Kibana for intuitive visualizations that help provide decision-makers with better insights. The book will later guide you through using Logstash with examples to collect, parse, and enrich logs before indexing them in Elasticsearch. By the end of this book, you will have comprehensive knowledge of advanced topics such as Apache Spark support, machine learning using Elasticsearch and scikit-learn, and real-time analytics, along with the expertise you need to increase business productivity, perform analytics, and get the very best out of Elasticsearch.

Summary

Woohoo! We have completed the final chapter. We glued together the knowledge we have learned and presented the result on the Kibana Visualize page. We believe that it is not easy to digest all the materials from this book. However, we are very confident that this book opens the way for readers who start out as beginners and quickly become skilled users. We have covered many advanced topics, such as Elasticsearch SQL, ES-Hadoop, ML, File Beat-Logstash-Elasticsearch-Kibana integration, and the Analytics plugin. Besides this, we have used the two most popular programming languages, Java and Python, to show the implementation of integrating Elasticsearch to build analytics applications. We hope that all readers will achieve great success in their careers with Elastic Stack.
