Introduction to OpenSearch®

OpenSearch is an open source search and analytics suite that serves as an alternative to Elasticsearch. It includes a search engine daemon, NoSQL database, and visualization interface. The distributed, full-text search engine is based on Apache Lucene with RESTful API interface support for JSON documents. Key components of OpenSearch include clusters and nodes, indices, REST API, and aggregations. Its primary use cases involve log analytics, real-time application monitoring, clickstream analytics, and search backend. To get started with OpenSearch, users can deploy it through the Aiven Console and connect using Python or NodeJS.
