What it is and what it does
opensearch-py is the official Python client for OpenSearch, a community-driven fork licensed under Apache v2.0. It provides a Pythonic interface to send requests to OpenSearch clusters over HTTP, handling connection pooling, serialization, and error handling transparently. The library wraps OpenSearch's REST API, allowing developers to perform search queries, index documents, manage indices, and administer clusters without writing raw HTTP calls.
The package is designed for applications that need to integrate search or analytics capabilities into Python services. It depends on urllib3 for HTTP connection management, requests for higher-level HTTP semantics, python-dateutil for timestamp handling, certifi for SSL certificate validation, Events for event handling, and opensearch-protobufs for protocol support. The library supports modern Python versions (3.10, 3.11, 3.12) and is marked production-stable, making it suitable for production deployments.
Use it for
- Building a search feature in a web application that queries documents stored in OpenSearch.
- Indexing application logs or events into OpenSearch for centralized logging and analysis.
- Automating cluster administration tasks such as creating indices or managing cluster state.
- Integrating OpenSearch analytics into data pipelines or ETL workflows.
- Migrating from Elasticsearch to OpenSearch with minimal code changes.
