OpenSearch Python Client
JSON →Official Python client for OpenSearch — AWS's Apache 2.0 fork of Elasticsearch 7.10. Current version: 3.1.0 (Mar 2026). API is nearly identical to elasticsearch-py v7 but NOT interchangeable — different package, different import. OpenSearch 1.x deprecated May 2025. v3.0 client released alongside OpenSearch 3.0. Major footgun: developers import elasticsearch instead of opensearch_py by mistake. Also compatible with Amazon OpenSearch Service (AWS managed).
