Elasticsearch is a widely used search engine in data analytics. It helps you to extract data really fast from data haystacks. It also helps to provide real-time analytics and data extraction. It is highly scalable, available, and multi-tenanted.

It also provides full text-based searches saved as a document. These documents, in turn, will be updated and modified based on any changes to the data. This, in turn, will provide a faster search and analysis of the data.
