About OpenSearch

OpenSearch is an open-source search engine project that originated in 2021, created by Amazon Web Services (AWS). It was a fork of Elasticsearch after Elastic changed its licensing model. OpenSearch was built to continue the development of a fully open-source, community-driven search and analytics platform. AWS took a leading role in maintaining the project, making it accessible to a wide array of developers and businesses.

OpenSearch is designed for both search and analytics, offering features similar to Elasticsearch. It allows users to index, search, and analyze large volumes of structured and unstructured data in real time. OpenSearch is widely used for log analytics, search engine infrastructure, and various other data-intensive applications. It supports distributed searches and can scale to handle complex data environments across numerous servers.

OpenSearch is actively maintained and continues to grow as an open-source alternative to Elasticsearch. It is widely adopted in enterprise environments, particularly within the AWS ecosystem. The project has gained a strong community of contributors, and it remains one of the leading platforms for search and analytics in large-scale data operations.
