What Is Elasticsearch?

Elasticsearch is a highly scalable and distributed search and analytics engine that is built on top of the Apache Lucene search library. It is designed to handle large volumes of structured, semi-structured, and unstructured data, making it well-suited for a wide range of use cases, including search engines, log analysis, e-commerce, and security analytics.

Elasticsearch uses a distributed architecture that allows it to store and process large volumes of data across multiple nodes in a cluster. Data is indexed and stored in shards, which are distributed across nodes for improved scalability and fault tolerance. Elasticsearch also supports real-time search and analytics, allowing users to query and analyze data in near real time.
