OpenSearch

OpenSearch is a community-driven, open-source search and analytics suite derived from Elasticsearch and Kibana. The project was initiated in 2021 by Amazon-Web-Services (AWS) following a licensing change in the original software. It is currently maintained under the OpenSearch-Foundation, which operates as part of the Linux-Foundation. The suite provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents.

Built on the powerful Apache-Lucene library, OpenSearch is designed for high-performance data retrieval and analysis. It is widely used for Log-Analytics, real-time application monitoring, and observability. The architecture supports a robust REST-API, allowing developers to interact with the engine programmatically. According to the official OpenSearch website, the software remains licensed under the Apache License, Version 2.0, ensuring it remains free to use and modify.

The ecosystem includes OpenSearch-Dashboards, a visualization tool that allows users to explore data and manage their clusters. It also supports various ingestion tools and plugins such as Fluent-Bit, Logstash, and Data-Prepper to facilitate complex data pipelines. Developers can contribute to or audit the project via its GitHub repository, which hosts the core engine and associated tools.
