OpenSearch is a free, open-source platform for data search, analysis, and visualization. It was developed as an evolution of the Elasticsearch and Kibana projects following licensing changes to those tools. Managed by the community and AWS, OpenSearch is designed for processing large volumes of data in real-time, offering users flexible analytical capabilities.

OpenSearch architecture

OpenSearch is based on a distributed architecture that enables efficient processing of large data sets. Its primary components include clusters consisting of one or more nodes. These clusters are responsible for data storage, indexing, and query processing. Thanks to this distributed model, data is replicated across nodes, ensuring high availability and fault tolerance.

Key elements of the architecture

Nodes are the fundamental computational units within a cluster. They can perform various roles, such as managing the cluster and monitoring the state of nodes and data distribution (master nodes), storing data and processing queries (data nodes), and redirecting queries to appropriate nodes (client nodes/coordinating nodes).

Data in OpenSearch is organized into indexes, which are logical storage units. Each index is divided into smaller parts called shards. Shards can be replicated, enhancing both performance and data security.

The OpenSearch search engine leverages an advanced search engine that enables fast full-text query processing and real-time data analysis. The engine supports various query types, such as filtering, aggregations, and layered searches.

OpenSearch provides a REST API, enabling seamless integration with other systems and applications. Users can perform queries, manage the cluster, and monitor its state using simple HTTP requests.
