What is Elasticsearch?
Elasticsearch is a search platform that ensures reliable and secure search along with data visualization and analysis. Written in Java and built on Apache Lucene, it has simple REST API, is scalable, fast, resilient, and agile. Elasticsearch is the prime component of Elastic Stack, commonly known as ELK Stack, which has Elasticsearch, Logstash, and Kibana with Beats, a lightweight shipping agent that sends data to Elasticsearch. Elasticsearch provides a unified view of data - metric data, APM data, log data, etc. that will be saved as JSON Document.
