How Is Elasticsearch Implemented?
Elasticsearch is a near real time search platform. More specifically, elasticsearch is a standalone database server, written in Java, that takes data in and stores it in a sophisticated format optimized for language based searches. Working with it is convenient as its main protocol is implemented with HTTP/JSON.

In this regard, what is the purpose of Elasticsearch?

Elasticsearch is one such NOSQL distributed database. ES (Elasticsearch) is a document-oriented database, designed to store, retrieve and manage document oriented or semi-structured data. When you use Elasticsearch you store data in JSON document form. Then you query them for retrieval.

Similarly, why is Elasticsearch fast? It is able to achieve fast search responses because, instead of searching the text directly, it searches an index instead. Additionally, it supports full-text search which is completely based on documents instead of tables or schemas.

Also to know is, where is Elasticsearch used?

Elasticsearch is used for a lot of different use cases: "classical" full text search, analytics store, auto completer, spell checker, alerting engine, and as a general purpose document store.

Is Elasticsearch a database?

Elasticsearch is a full-text, distributed NoSQL database. In other words, it uses documents rather than schema or tables. It's a free, open source tool that allows for real-time searching and analyzing of your data.

Related Question Answers

Why use Elasticsearch instead of SQL?

Elasticsearch is actually a JSON document store built upon the Apache Lucene search engine. There are other differences, of course: Lucene is better at managing large numbers of indexes, and can handle complex index searches much faster than a comparable SQL database can.

Where is Elasticsearch data stored?

If you're on Windows or if you've simply extracted ES from the ZIP/TGZ file, then you should have a data sub-folder in the extraction folder. According to the documentation the data is stored in a folder called "data" in the elastic search root directory.
