| # DataFlow & DataJob
 | |
| 
 | |
| ## Why Would You Use DataFlow and DataJob?
 | |
| 
 | |
| The DataFlow and DataJob entities are used to represent data processing pipelines and jobs within a data ecosystem. They allow users to define, manage, and monitor the flow of data through various stages of processing, from ingestion to transformation and storage.
 | |
| 
 | |
| ### Goal Of This Guide
 | |
| 
 | |
| This guide will show you how to
 | |
| 
 | |
| - Create a DataFlow.
 | |
| - Create a Datajob with a DataFlow.
 | |
| 
 | |
| ## Prerequisites
 | |
| 
 | |
| For this tutorial, you need to deploy DataHub Quickstart and ingest sample data.
 | |
| For detailed steps, please refer to [Datahub Quickstart Guide](/docs/quickstart.md).
 | |
| 
 | |
| ## Create DataFlow
 | |
| 
 | |
| <Tabs>
 | |
| <TabItem value="python" label="Python" default>
 | |
| 
 | |
| ```python
 | |
| {{ inline /metadata-ingestion/examples/library/create_dataflow.py show_path_as_comment }}
 | |
| ```
 | |
| 
 | |
| </TabItem>
 | |
| </Tabs>
 | |
| 
 | |
| ## Create DataJob
 | |
| 
 | |
| DataJob must be associated with a DataFlow. You can create a DataJob by providing the DataFlow object or the DataFlow URN and its platform instance.
 | |
| 
 | |
| <Tabs>
 | |
| <TabItem value="python" label="Create DataJob with a DataFlow Object" default>
 | |
| ```python
 | |
| {{ inline /metadata-ingestion/examples/library/create_datajob.py show_path_as_comment }}
 | |
| ```
 | |
| 
 | |
| </TabItem>
 | |
| <TabItem value="python" label="Create DataJob with DataFlow URN">
 | |
| ```python
 | |
| {{ inline /metadata-ingestion/examples/library/create_datajob_with_flow_urn.py show_path_as_comment }}
 | |
| ```
 | |
| </TabItem>
 | |
| </Tabs>
 | |
| 
 | |
| ## Read DataFlow
 | |
| 
 | |
| ```python
 | |
| {{ inline /metadata-ingestion/examples/library/read_dataflow.py show_path_as_comment }}
 | |
| ```
 | |
| 
 | |
| #### Example Output
 | |
| 
 | |
| ```python
 | |
| >> DataFlow name: example_dataflow
 | |
| >> DataFlow platform: urn:li:dataPlatform:airflow
 | |
| >> DataFlow description: airflow pipeline for production
 | |
| ```
 | |
| 
 | |
| ## Read DataJob
 | |
| 
 | |
| ```python
 | |
| {{ inline /metadata-ingestion/examples/library/read_datajob.py show_path_as_comment }}
 | |
| ```
 | |
| 
 | |
| #### Example Output
 | |
| 
 | |
| ```python
 | |
| >> DataJob name: example_datajob
 | |
| >> DataJob Flow URN: urn:li:dataFlow:(airflow,PROD.example_dag,PROD)
 | |
| >> DataJob description: example datajob
 | |
| ```
