Elasticsearch 7. X is the first edition of Elasticsearch to get you started! Spoofer is the developer of Elasticsearch 7.

🎙️ Author introduction

Spoofer, back office r&d engineer. Usually keen on technology sharing and research all kinds of middleware source code and implementation, boring also play tianchi middleware competition, although the results are general.

Over the years, I have focused on the research and development of background services, as well as the components and systems related to large data. In recent years, I worked as a background R&D engineer in a K12 education company, responsible for and participating in the architecture design, core components and service implementation of the company’s K12 cloud education system.

Why is 🔥Elasticsearch so popular?

Today, with the rapid development of the Internet, big data and artificial intelligence, the storage and retrieval of massive data has become an urgent need. After all, at some level, whoever controls the data controls the initiative. Yes, there can be a lot of gold and silver in seemingly random data, but only if you have the ability to store, process, retrieve and present it.

Elasticsearch is a new kid on the block in the search engine space and has grown tremendously since its launch. Open source, distributed and RESTFul, it has become the most popular search engine in recent years, ranking no. 1 in THE “Weapons” list of DB-Engines, as shown below:

In addition to search, Elasticsearch, Kibana, and Logstash ELK can also be used for log collection, analysis, and monitoring.

Elasticsearch is now used by many enterprises and teams, so why is Elasticsearch so popular? From the Elasticsearch website you can see some of these advantages.

  • Answers to all kinds of questions can be found in the data. With Elasticsearch you can perform and merge multiple types of searches (structured data, unstructured data, geographic location, metrics) in any way you want.
  • Incredibly fast. You can use and access all your data at amazing speed.
  • High scalability. It scales horizontally to handle a large number of events per second, while automatically managing how indexes and queries are distributed across the cluster for extremely smooth operation.
  • Security and reliability. Elasticsearch can detect hardware failures, network partitions, and more for you, and ensure the security and availability of your cluster and data. With cross-cluster replication, secondary clusters can be used as hot backup at any time.

With Elasticsearch, you can easily, safely, and reliably store, search, and analyze large amounts of data.

🏠 Set ideas and framework

This four-part tutorial introduces you to the core technologies of Elasticsearch 7.x. The main knowledge points include basic concepts, the use of common APIS, the underlying principles and ideas of core features, cluster management and tuning, source code reading and other knowledge. The mind map for the entire volume is as follows:

Elasticsearch 7. X: Elasticsearch 7. X: Elasticsearch 7. X: Elasticsearch 7. After understanding these principles, we will learn how to deploy, operate and maintain small clusters online, and work with you to build a simple ELK system. Finally, we will set up the source code reading environment and read the source code of some modules with you.

🤔 What will you learn?

Therefore, through most of this volume 4 study, you can gain:

  • Proficient in Elasticsearch to solve search requirements;
  • Improved Elasticsearch cluster o&M and tuning capabilities.
  • – Basic implementation of Elasticsearch core technology
  • Strong grasp of source code reading and debugging skills.

This course will help you build your own search, data analysis, and logging systems for ElasticSearch. Truly apply what you have learned.

💡 for whom to learn?

  • For those interested in Elasticsearch or search engines.
  • For those of you who know and use Elasticsearch, now want to learn more about Elasticsearch.
  • Students who are ready to engage in data search and analysis related work.
  • Students engaged in Elasticsearch cluster operation and maintenance.

I write a small volume of the original intention is because of their own learning to take a lot of detachs, heart to heart, hope to have such a data to just start or a little basic students for consulting and learning. So, we’re looking forward to seeing you join us in this tutorial to uncover the core technology of Elasticsearch 7.x.
