What is Elasticsearch?
Elasticsearch is an open source, distributed, RESTful search and analytics engine built on Apache Lucene. It is used for full-text search, structured search, analytics, and all three in combination.
Key features of Elasticsearch include:
- Distributed and highly scalable - can scale to hundreds of servers and petabytes of structured and unstructured data
- Real-time search and analytics - search results and analytics are updated in real-time as data changes
- Powerful querying via the Query DSL - comprehensive query language supports structured, unstructured, geo, metric, and other queries
- RESTful API - all operations are performed via a RESTful API for easy integration
- Document oriented - stores entire objects or documents which makes it schema-free and easier to evolve data models
- Open source under the Apache license
Elasticsearch sees wide use in log analytics, full-text search, security analytics, business intelligence, application monitoring and many other use cases involving large amounts of data that needs to be indexed and analyzed in real-time. It integrates seamlessly with popular data stores like MongoDB and PostgreSQL.
