# mypy-boto3-opensearchserverless — Type annotations for boto3 OpenSearchServiceServerless 1.43.17 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 255.9K/mo

## What it is and what it does

This package is a type stub library that adds static type information to boto3's OpenSearchServiceServerless client. It is generated automatically from boto3 service definitions using mypy-boto3-builder and provides complete type annotations for client methods, request shapes, and response objects.

When installed, it enables IDEs (VSCode, PyCharm, Emacs, Sublime Text) and type checkers (mypy, pyright) to understand boto3 OpenSearchServiceServerless calls, offering code completion and catching type errors at development time rather than runtime. It has no runtime behavior—it is purely a stub library for development and static analysis. The package supports Python 3.9 through 3.14 and depends only on typing-extensions.

Use it for:

- Enable IDE autocomplete and inline documentation for OpenSearchServiceServerless client methods while writing boto3 code.
- Catch type mismatches in boto3 OpenSearchServiceServerless calls during development with mypy or pyright.
- Provide explicit type hints for OpenSearchServiceServerlessClient in function signatures and variable annotations.
- Use in CI/CD pipelines to enforce type safety on AWS SDK calls before deployment.
- Improve code maintainability by documenting expected parameter and return types for OpenSearchServiceServerless operations.

## Worth the install?

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

Provides type annotations and IDE autocompletion for boto3's OpenSearchServiceServerless client, enabling static type checking with mypy, pyright, and editor support.

Yes, if you use boto3 to interact with OpenSearchServiceServerless. It has low install friction, no runtime overhead, is actively maintained, carries no security vulnerabilities, and is licensed permissively. Install it in development environments to catch bugs early; use TYPE_CHECKING guards if you want to exclude it from production dependencies.

## Install

pip install mypy-boto3-opensearchserverless
uv add mypy-boto3-opensearchserverless
poetry add mypy-boto3-opensearchserverless

## Installing mypy-boto3-opensearchserverless

Before you install: Low friction install with a single lightweight runtime dependency (typing-extensions). Actively maintained with recent releases; the package is generated automatically from boto3 service definitions.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects without requiring source disclosure.

Quickstart:

# Install type stubs
python -m pip install 'boto3-stubs[opensearchserverless]'

# Use in code
from boto3.session import Session
from mypy_boto3_opensearchserverless import OpenSearchServiceServerlessClient

client: OpenSearchServiceServerlessClient = Session().client("opensearchserverless")

Requires boto3 to be installed separately; type checking works best with mypy, pyright, or an IDE with type-aware language server support.

Verify before relying:

- Whether performance impact on PyCharm is acceptable for your project (documentation notes slow performance on Literal overloads).
- Whether the lite variant (boto3-stubs-lite) would be more suitable for your IDE or memory constraints.
