OpenSearch

OpenSearch is the Apache 2.0-licensed, community-driven search and analytics suite (a fork of Elasticsearch and Kibana 7.10) for scalable data ingestion, search, and visualization.

OpenSearch is a powerful, distributed, and open-source suite for search and analytics, built on Apache Lucene. It originated as a community-led fork of Elasticsearch and Kibana (version 7.10), ensuring a permissive Apache 2.0 license. The technology handles high-volume data ingestion and provides fast, full-text search, log analytics, and real-time data exploration at scale. Key components include the OpenSearch engine itself and OpenSearch Dashboards (for visualization and management), supporting critical use cases like anomaly detection, vector search, and complex query DSL (Domain-Specific Language) operations.
