Declares the Airbyte Protocol.
Decision gist · record as of 2026-08-14
Yes, if you are building or extending Airbyte connectors or integrations that require protocol-compliant message handling. The permissive MIT license, low dependency footprint, and stable API make it safe to adopt. However, the 413-day release gap warrants checking whether active development continues or whether you need to pin to version 0.18.0 for stability. Not necessary for users simply running Airbyte connectors.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- Low install friction with a single dependency on pydantic.
- Maintenance status is aging—last release was 413 days ago, though the repository remains active with recent commits as of 2026-01-27.

What it is and what it does
airbyte-protocol-models-pdv2 is a Python package that declares and implements the Airbyte Protocol—the standard message format used by Airbyte data integration connectors to communicate. It provides serializable data models built on pydantic, allowing connectors and integration tools to construct, validate, and exchange protocol-compliant messages. The package is part of Airbyte's core infrastructure and is typically used as a dependency rather than directly in application code.
The package supports Python 3.9 and later, has low install friction (only pydantic as a runtime dependency), and is distributed as a wheel. While the project repository remains active, the package itself has not seen a release in over a year, suggesting it may be in a stable or maintenance-only state rather than under active feature development.
Use it for
- Building custom Airbyte connectors that need to emit protocol-compliant messages to the Airbyte platform.
- Integrating with Airbyte's data pipeline infrastructure where protocol message validation is required.
- Testing or debugging Airbyte connector behavior by constructing and inspecting protocol messages locally.
- Developing tooling or utilities that need to parse or generate Airbyte Protocol messages.
