DataHub is an open-source metadata platform for the modern data stack. The Python client (acryl-datahub) provides utilities for ingesting metadata, interacting with the DataHub API, and managing data lineage. As of version 0.12.1, the package has transitioned from 'datahub' to 'acryl-datahub' on PyPI. The dummy package 'datahub' 0.999.1 is a placeholder and should be avoided in favor of 'acryl-datahub'.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

DataHubRestEmitter

✓ from datahub.emitter.rest_emitter import DataHubRestEmitter

✗ from datahub import DataHubRestEmitter

The recommended import path uses the emitter submodule.

DataHubGraph

✓ from datahub.ingestion.graph.client import DataHubGraph

✗ from datahub.graph import DataHubGraph

The correct module is datahub.ingestion.graph.client.

Quickstart: Emit a dataset metadata change event.

import os from datahub.emitter.rest_emitter import DataHubRestEmitter from datahub.metadata.schema_classes import DatasetPropertiesClass # Create an emitter to DataHub server = os.environ.get('DATAHUB_SERVER', 'http://localhost:8080') token = os.environ.get('DATAHUB_TOKEN', '') emitter = DataHubRestEmitter(gms_server=server, token=token) # Emit a dataset metadata change emitter.emit_mcp( entity_urn='urn:li:dataset:(urn:li:dataPlatform:hive,test_dataset,PROD)', aspect=DatasetPropertiesClass(description='Test dataset') ) print('Metadata emitted successfully')

Known issues

deprecatedThe 'datahub' package on PyPI (version 0.999.1) is a dummy placeholder. Install 'acryl-datahub' instead.

fix

Run: pip uninstall datahub && pip install acryl-datahub

affects: >=0.999.1

breakingIn older versions (pre-0.9.0), the import paths were different. The emitter was at 'datahub.emitter.rest_emitter' but now uses async/await patterns.

fix

Upgrade to latest acryl-datahub and use new import paths.

affects: <0.9.0

gotchaWhen using the emitters, ensure you call .emit() correctly. The synchronous emitter no longer exists; use async or use DataHubRestEmitter which is synchronous.

fix

Use DataHubRestEmitter for synchronous emits or use the async emitter with event loop.

affects: >=0.9.0
