Smithy components for Amazon Event Streams.
Decision gist · record as of 2026-08-14
No, not for production. This package is explicitly pre-alpha with unstable interfaces and a warning against production use. Install only if you are generating Smithy clients that require event stream support and are willing to accept breaking changes as the package matures.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.12 or newer; intended for use as a dependency within Smithy-generated clients, not as a standalone library.
- Low install friction with a single pure-Python dependency (smithy-core).
- Active maintenance with recent commits, though the package remains in pre-alpha status and explicitly warns that all interfaces are subject to change.

What it is and what it does
This package provides low-level Python components for handling Amazon Event Streams as part of the Smithy SDK generation framework. It is designed to be used as a runtime dependency in service clients generated by the Smithy Python code generator, enabling asynchronous communication over event streams using the restJson1 protocol.
The package is currently in pre-alpha development and explicitly warns that all interfaces are subject to change. It depends only on smithy-core and supports Python 3.12 and newer. It is not intended for production use yet, and several features remain unimplemented. Developers should treat this as an unstable, experimental component that may undergo breaking changes.
Use it for
- Building Smithy-generated Python clients that need to handle AWS event stream operations.
- Integrating event stream communication into asynchronous service clients for non-AWS Smithy services.
- Prototyping or testing event stream protocols before production deployment.
