OpenSearch Overview
What is OpenSearch?
OpenSearch is a community-driven, open source search and analytics suite derived from Elasticsearch 7.10.2. It includes a distributed search and analytics engine called OpenSearch, and OpenSearch Dashboards, which provides visualization and user interface capabilities. OpenSearch enables you to ingest, search, analyze, and visualize your data at scale.
Key Features of OpenSearch
Distributed Search Engine
OpenSearch provides powerful full-text search capabilities across distributed clusters. It can handle large volumes of data and provides near real-time search results. The distributed nature ensures high availability and scalability of your search operations.
Data Analytics
Beyond search, OpenSearch offers robust analytics capabilities. You can perform complex aggregations, statistical analyses, and create detailed visualizations of your data. This makes it ideal for log analytics, application monitoring, and business intelligence applications.
Security Features
OpenSearch includes comprehensive security features including:
- Fine-grained access control
