Type annotations for boto3 EMR 1.43.50 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes, if you use boto3 to manage AWS EMR clusters and want type safety and IDE support. Install friction is minimal, maintenance is active, and the MIT license is unrestricted. The package adds no runtime overhead (it is stubs-only) and integrates transparently with existing boto3 code. Recommended for any team using EMR automation.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; boto3 must be installed separately in your environment.
- Low install friction with a single lightweight runtime dependency (typing-extensions).
- Actively maintained with recent releases; repository shows 670 stars and last commit on 2026-06-22.

What it is and what it does
mypy-boto3-emr is a type-stub package that adds complete type annotations to boto3's EMR service client. It enables IDE autocomplete, type checking with mypy and pyright, and catches potential bugs at development time rather than runtime. The package is generated from boto3 1.43.50 and works with VSCode, PyCharm, Emacs, Sublime Text, and other editors that support Python language servers.
You install it alongside boto3 and use it transparently—your boto3 code works exactly as before, but now your IDE knows the types of EMR client methods, their parameters, return values, paginators, and waiters. The package includes explicit type annotations for EMRClient, paginators (ListClustersPaginator, ListInstancesPaginator, etc.), and waiters, letting you write safer EMR automation scripts without manual type hints.
Use it for
- Add type checking to EMR cluster management scripts using mypy or pyright in CI/CD pipelines.
- Get IDE autocomplete and inline documentation for EMR client methods while writing boto3 code.
- Catch typos and incorrect parameter names in EMR API calls before runtime.
- Use explicit type annotations for EMRClient in large codebases to improve code clarity and maintainability.
- Enable type-safe pagination over EMR resources (clusters, instances, steps) with full IDE support.
