DataHub Actions Framework

Event-driven framework for responding to real-time changes in the DataHub metadata graph. The Actions Framework allows you to configure event sources, transformations, and actions using YAML configuration files. It enables seamless integration of DataHub into a broader event-based architecture by consuming Metadata Change Logs and Platform Events.

Documentation Provider Profile APIs.io AsyncAPI GitHub

DataHub Actions Framework is one of 11 APIs that DataHub publishes on the APIs.io network, described by an AsyncAPI event-driven specification.

Tagged areas include Actions, Automation, Event, and Real-Time. The published artifact set on APIs.io includes API documentation, a getting-started guide, and an AsyncAPI specification.

This event API exposes 3 operations across 3 channels, and defines 7 schemas. It is described by AsyncAPI 2.6.0, at version 1.4.0.

The API connects through a single server, {kafkaHost}:{kafkaPort} (kafka).

Where this information came from

This is an independent, third-party profile of DataHub Actions Framework, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
