Microsoft Purview is an advanced data governance solution that allows organizations to discover, understand, and manage their data assets across various sources. As part of its feature set, Purview supports the concept of data lineage, which provides insights into the origins, transformations, and destinations of data within an organization’s data ecosystem. In this article, we will explore how to push new or updated data lineage to Microsoft Purview using the available tooling and APIs.
To get started, you need to create a Data Map in Purview that represents your data ecosystem. This involves defining the metadata sources, data sources, and data transformations that are relevant to your organization. You can use the Purview Studio user interface or the REST API to create and configure the Data Map.
Metadata sources such as Azure Data Factory, Azure Synapse Analytics, or Apache Atlas can provide information about the data assets and their lineage. You can configure these sources to push metadata and lineage information to Purview. The exact steps and configurations vary depending on the metadata source, but Purview provides comprehensive documentation for each specific integration.
In addition to metadata sources, you can also push lineage information directly from the data sources themselves. By integrating with the appropriate connectors, Purview can capture lineage information from sources like Azure SQL Database, Azure Data Lake Storage, or Azure Blob Storage. Again, the specific steps and configurations depend on the data source, and the documentation provides detailed guidance for each integration.
Data transformations play a crucial role in understanding the lineage of your data. Tools like Azure Data Factory allow you to define and orchestrate complex data transformation workflows. By configuring Data Factory to log lineage information and integrating it with Purview, you can push the transformation details to the Data Map. This helps build a comprehensive lineage view for your data assets.
In addition to the integrations mentioned above, you can also use the Purview REST API to push new or updated data lineage. The API provides endpoints to create or update entities, relationships, classifications, and more. You can use the API to programmatically push lineage information from custom data sources, extract lineage information from external tools, or automate the ingestion process. The API documentation provides extensive details about the available endpoints and their usage.
It is important to note that pushing new or updated data lineage to Purview is an ongoing process. As your data ecosystem evolves and new data assets are added or modified, it is crucial to keep the Data Map up to date. By leveraging the integrations and APIs provided by Purview, you can ensure that your data lineage remains accurate and reflects the current state of your data assets.
As you work with Purview, make sure to refer to the official Microsoft documentation for detailed instructions and examples. The documentation provides step-by-step guidance for configuring the integrations, using the REST API, and managing the Data Map effectively. Stay up to date with the latest Purview features and releases, as Microsoft regularly introduces enhancements to improve data lineage capabilities.
In conclusion, Microsoft Purview is a powerful data governance tool that enables organizations to push new or updated data lineage information. By leveraging integrations with metadata sources, data sources, and data transformation tools, as well as utilizing the Purview REST API, you can ensure that your data lineage accurately reflects your data ecosystem. Stay informed with the official documentation to maximize the benefits of Purview’s data lineage capabilities.

Great post on pushing new or updated data lineage to Microsoft Purview! Helped me with my DP-203 preparations.
How scalable is Purview for enterprise-level operations?
Purview is designed to scale with large enterprise needs, supporting extensive metadata catalogs and complex data landscapes.
Can someone provide guidance on securing data lineage information in Purview?
You’ll need to carefully configure Azure role-based access control (RBAC) and Purview’s own access policies to secure lineage information.
Agreed, defining clear access roles and policies are key to ensuring data security.
Amazing post! Helped clarify many doubts.
Very informative. Appreciate it!
I think this could have been explained a bit more clearly, especially the API integration part.
Could you provide some example use-cases where data lineage in Purview has been critical?
One common use-case is regulatory compliance, where traceability of data is crucial. Another is root cause analysis for data issues.
Insightful article. Thanks for the help!
Thanks for the detailed explanation! This will be a big help for my data engineering project.
Anybody faced issues with Purview’s performance on large datasets?
Batch processing and partitioning the data can also improve performance significantly.
Yes, performance can degrade with extremely large datasets. Optimizations and indexing can help mitigate some of these challenges.
How do you handle versioning of data lineage in Purview?
Purview manages versions for metadata, ensuring that you can track changes over time. You can view and revert to previous versions if needed.
Thank you for sharing this knowledge. It’s very helpful.
Excellent! Helped me streamline our data pipeline workflows.
Thanks a bunch! This really simplified things for me.
What are the steps to manually update data lineage in Purview?
You can manually update data lineage either through the Purview portal or by using the Purview REST API to push metadata records.
My project could benefit greatly from this! Fantastic work!
What are the common challenges faced while integrating Purview with existing systems?
Also, permissions and security configurations might take some time to get right, especially in a complex environment.
Schema mismatches and ensuring data consistency can be tricky. Proper mapping and validation are critical.
I appreciate the effort put into creating this guide. Thanks!
Does anyone have experience automating the process with Azure Data Factory?
You would need to create a custom activity within ADF to achieve that. It’s quite powerful once setup correctly.
Yes, you can use Azure Data Factory pipelines to push data lineage metadata by integrating with the Purview REST API.
