# types-aiobotocore-opensearch — Type annotations for aiobotocore OpenSearchService 3.9.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 82.4K/mo

## What it is and what it does

This package is a type-stub library that adds static type information to aiobotocore's OpenSearchService client. It is generated from the aiobotocore 3.9.0 API surface using mypy-boto3-builder and provides complete type annotations for client methods, paginators, and service resources. When installed, it enables IDEs (VSCode, PyCharm, Emacs, Sublime Text) and type checkers (mypy, pyright) to offer autocomplete suggestions and catch type errors in your OpenSearch client code without requiring explicit type annotations in your source.

The package is a stub-only library—it contains no runtime code, only type definitions. It works alongside aiobotocore, which you install separately and use to make actual async API calls. The stubs are compatible with Python 3.9 through 3.14 and are actively maintained, with the latest release less than two weeks old. Installation is straightforward with minimal dependencies, making it a low-friction addition to projects using aiobotocore for OpenSearch.

Use it for:

- Enable IDE autocomplete and type hints when writing aiobotocore OpenSearch client code in VSCode or PyCharm.
- Catch type errors in OpenSearch API calls during development using mypy or pyright without runtime overhead.
- Document expected parameter types and return values for OpenSearchService operations in your codebase.
- Support code review and refactoring by providing precise type information for OpenSearch client methods.
- Use in TYPE_CHECKING blocks to add type safety to production code without adding a runtime dependency.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type annotations and IDE autocomplete support for aiobotocore's OpenSearchService client, enabling static type checking with mypy, pyright, and compatible editors.

Yes. Install this if you use aiobotocore to interact with OpenSearch and want static type checking or IDE autocomplete. The package is actively maintained, has no known vulnerabilities, carries a permissive MIT license, and adds negligible install friction. The only caveat is PyCharm users may experience performance issues with the full type stubs (the documentation recommends the lite variant as a workaround), but VSCode, mypy, and pyright users will see immediate benefit.

## Install

pip install types-aiobotocore-opensearch
uv add types-aiobotocore-opensearch
poetry add types-aiobotocore-opensearch

## Installing types-aiobotocore-opensearch

Before you install: Low friction installation with a single lightweight dependency (typing-extensions). Package is actively maintained with recent releases and no known vulnerabilities.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects with minimal obligations.

Quickstart:

pip install types-aiobotocore-opensearch

from aiobotocore.session import get_session
from types_aiobotocore_opensearch import OpenSearchServiceClient

session = get_session()
async with session.create_client("opensearch") as client:
    client: OpenSearchServiceClient

Requires Python 3.9 or later; aiobotocore must be installed separately to use the client at runtime.

Verify before relying:

- Whether performance impact on PyCharm remains significant after the noted PY-40997 issue resolution.
- Exact coverage of OpenSearchService operations and paginators in the generated type stubs.
