Despite appearing to fit mostly batch processing jobs, OpenLineage provides comprehensive lineage tracking for both batch and streaming job models.

Apache Flink is a powerful stream processing engine widely adopted in the industry. Flink jobs have been capable of emitting OpenLineage events for already two years. However, it is a recent joint effort of Flink and OpenLineage communities that will bring this integration into the new era.

In the world of data lineage, it's essential to have a reliable and flexible way to send events to multiple destinations. This is where the Composite Transport comes in, a powerful feature in OpenLineage that allows you to aggregate multiple transports and send events to multiple targets in a defined order.

The OpenLineage community has frequently highlighted the need for a more flexible and scalable approach to configuration management, particularly through environment variables. Many users reported challenges in maintaining separate configuration files across development, testing, and production environments. In response, the 1.23.0 release introduces dynamic environment variables—addressing these concerns head-on by simplifying the configuration process, reducing code changes, and improving security across different environments.

In this guide, we'll explore how to leverage dynamic environment variables to simplify OpenLineage configuration, enhance flexibility, and improve security.

Note: this event is now hybrid.

Join us on Thursday, September 12th, 2024, from 6:00-9:00 pm PT at the Astronomer offices in San Francisco or on Zoom to learn more about the present and future of OpenLineage. Meet other members of the ecosystem, learn about the project’s goals and fundamental design, and participate in a discussion about the future of the project. Bring your ideas and vision for OpenLineage!

Join us on Tuesday, March 19th, 2024, from 5:30-8:00 pm at the Microsoft New England Conference Center in Boston to learn more about the current state of lineage in general and static lineage support in data catalogs in particular. Bring your ideas and vision for data lineage!

At this year's Kafka Summit in London, two project committers, Paweł Leszczyński and Maciej Obuchowski, will give a talk entitled OpenLineage for Stream Processing on March 19th at 2:00 PM GMT.

As the abstract available on the summit website says, the talk will cover some of the 'many useful features completed or begun' recently related to stream processing, including:

• a seamless OpenLineage & Apache Flink integration,
• support for streaming jobs in Marquez,
• progress on a built-in lineage API within the Flink codebase.

As the abstract goes on to say,

Cross-platform lineage allows for a holistic overview of data flow and its dependencies within organizations, including stream processing. This talk will provide an overview of the most recent developments in the OpenLineage Flink integration and share what’s in store for this important collaboration. This talk is a must-attend for those wishing to stay up-to-date on lineage developments in the stream processing world.

Register and attend this interesting talk if you can. And keep an eye out for an announcement about a recording if and when one becomes available.

Thanks, Maciej and Paweł, for spreading the word about these exciting developments in the project.

Join us on Wednesday, January 31st, 2024, from 6:00-8:00 pm at the Confluent offices in London to learn more about the current state of lineage in general and streaming support in particular. Bring your ideas and vision for OpenLineage!

Join us on Wednesday, November 29th, 2023, from 17:30-20:30 CET in Warsaw, Poland, to contribute to a discussion of the future of OpenLineage. On the tentative agenda:

1. Mary Idamkina on OpenLineage in GCP Dataplex
2. Paweł Leszczynski on recent developments in the Spark Integration
3. Jakub Dardziński on Extracting lineage from PythonOperator - how come this is possible?
4. Paweł Leszczynski on How to Become a Spark-OpenLineage Contributor in 5 Steps

In the ever-evolving landscape of data management and governance, organizations constantly seek innovative solutions to streamline their processes, foster collaboration, and maximize the value of their data assets. Metaphor, born out of the minds behind LinkedIn's DataHub, has emerged as a modern data catalog and social platform for data. We take a unique approach by combining technical metadata with social collaboration, making data governance accessible and engaging for everyone in the organization. In this blog post, we explain the motivation behind Metaphor’s adoption of OpenLineage, delve into the integration methodology, and discuss its current status and benefits.
