# mypy-boto3-osis — Type annotations for boto3 OpenSearchIngestion 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 243.4K/mo

## What it is and what it does

mypy-boto3-osis is a type-stub package that bridges boto3's OpenSearchIngestion service and Python's static type checkers. It provides complete type annotations for the OpenSearchIngestion client, paginators, and service resources, enabling IDEs and type checkers like mypy and pyright to validate your code and offer autocomplete suggestions as you write.

The package is generated automatically from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with VSCode (via Pylance), PyCharm, Emacs, Sublime Text, and command-line tools. It's designed as a development-only dependency—you can use TYPE_CHECKING guards to keep it out of production code. Installation is straightforward (a single wheel with typing-extensions as its only runtime dependency), and it requires Python 3.9 or later.

Use it for:

- Enable IDE autocomplete and inline documentation for boto3 OpenSearchIngestion API calls in VSCode or PyCharm.
- Catch type errors in OpenSearchIngestion client usage before runtime using mypy or pyright in CI/CD.
- Document expected argument and return types for OpenSearchIngestion operations in your codebase without manual annotations.
- Use paginator types explicitly when iterating over OpenSearchIngestion API results.
- Migrate from untyped boto3 code to fully type-checked AWS SDK usage incrementally.

## Worth the install?

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

Provides type annotations and IDE autocomplete support for boto3's OpenSearchIngestion service, enabling static type checking in mypy, pyright, and IDEs like VSCode and PyCharm.

Yes, if you use boto3's OpenSearchIngestion service and want static type checking or IDE autocomplete. Low install friction, active maintenance, no security vulnerabilities, and permissive MIT license make it a straightforward addition to development environments. Use TYPE_CHECKING guards if you want to keep it out of production dependencies.

## Install

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

## Installing mypy-boto3-osis

Before you install: Low friction: pure Python wheel with a single runtime dependency (typing-extensions). Actively maintained as of 2026-06-22 with 670 repository stars. Generated from mypy-boto3-builder 8.12.0, part of a well-established boto3 stubs ecosystem.

License in practice: MIT license (permissive) means you can use this freely in commercial and private projects with minimal restrictions—no copyleft obligations.

Quickstart:

# Install
python -m pip install mypy-boto3-osis

# Use in code
from boto3.session import Session
from mypy_boto3_osis import OpenSearchIngestionClient

client: OpenSearchIngestionClient = Session().client("osis")
# Type checking and IDE autocomplete now work

Requires Python 3.9 or later; boto3 must be installed separately (not a declared runtime dependency, but required to use the types).

Verify before relying:

- Whether boto3 1.43.0 is the minimum or maximum compatible version for this stub package.
- Performance impact in PyCharm (docs mention potential slowness with Literal overloads; whether this affects OpenSearchIngestion specifically is unclear).
- Whether the lite variant (boto3-stubs-lite) is recommended for this service as an alternative to the full stubs.
