How To Run Databricks Notebook From Azure Data Factory

Running a Databricks Notebook from Azure Data Factory

To run a Databricks notebook from Azure Data Factory, follow these steps:

1. Create a Data Factory: First, ensure you have an Azure Data Factory instance. If not, create one through the Azure portal.
2. Create a Linked Service: In Azure Data Factory, create a linked service to your Azure Databricks workspace. This establishes a connection between Data Factory and Databricks.
3. Create a Pipeline: In the Data Factory UI, create a new pipeline. This pipeline will be used to execute the Databricks notebook.
4. Add Databricks Notebook Activity: In the pipeline, add a Databricks Notebook activity. This activity will run your notebook.
5. Configure Notebook Activity: Configure the notebook activity by selecting the linked service and specifying the path to your Databricks notebook.
6. Pass Parameters (Optional): If your notebook requires parameters, you can pass them from the pipeline using the @pipeline().parameters syntax.
7. Trigger the Pipeline: Once configured, trigger the pipeline to run. You can do this manually or schedule it for automated execution.
8. Monitor the Pipeline Run: After triggering the pipeline, monitor its status in the Data Factory UI to ensure successful execution.
