• Dataset Namespace Resolver
  • Naming convention for datasets - when hostname is used for uniquely identifying a dataset, redundant servers can be an issue.
  • Resolves several namespaces into the same dataset - e.g. kafka1, kafka2, kafka3.
  • Discussed the use case where there are several names for the same dataset in different technologies (e.g. dbt, Athena, Spark and Databricks all list different namespaces for the same dataset). The tool may or may not know what the underlying data location is (e.g. S3 bucket).
    • The Dataset Namespace Resolver will work in this case

    - Eric, Suraj, and Damien introduce themselves and express their excitement to be part of the call.

Agenda Overview and New Committer Introduction
    - Michael Robinson outlines the agenda for the call, including announcements, recent releases, and discussion items.
    - Michael Robinson announces a change in the Zoom link and welcomes a new committer, Damien from Booking.com, who has made significant contributions to the project.
    - Harel and Michael Robinson express their gratitude for Damien's contributions and explain how he added support for multiple Spark versions for the integration, which saved a lot of time and effort for the community.

Upcoming Events
    - Michael Robinson announces a data lineage meet up on March 19th at the Microsoft New England Conference Center, co-sponsored by Astronomer and Collibra. More details and sign-up link available on Meetup.com.
    - An updated agenda and information about speakers will be provided soon.
    - Michael Robinson informs about an exciting talk at Kafka Summit on March 19th called "Open Lineage for Stream Processing" by Baimache and Pavel. There will also be a data standardization panel moderated by Julien at Data Council on March 27th, with participants to be finalized soon.

Recent Releases and Contributions
    - Michael Robinson shares about the successful first London meetup with speakers from Decathlon, Confluent, and Astronomer. Decathlon's lineage graph was showcased, and more details about their architecture and use case will be shared in the future.
    - Open Lineage 1.8 was released with contributions from Damian, Mata, Meta, Bertel, Peter, and Natalie.
   - Michael Robinson thanks all contributors and welcomes Matea's first contributions to the project. Open Lineage 1.8 can be read about on the GitHub repo and docs.
    - Maciej is asked if he would like to share his screen.

UI Feature and Streaming Integration
    - Maciej explains two topics for the call: a store and a description of how they think of job-specific park. He discusses the job hierarchy and how they can answer questions about why a job ran at a certain time.
    - He gives an example of a parent job and how it schedules events. He explains that for a spark job, there can be multiple events and actions, but they want to simplify it to one event at the start and one at the end with each action having a parent job.
    - He gives a complex example of a sequence of events for a spark application. He explains that open consumers can collapse the information they receive for a simplified view of the spark application.
    - Maciej explains the new UI feature that allows for a top-level view of data in spark levers, without distinguishing the internal actions. He also mentions the higher level execution feature that allows users to see what is scheduled across the platform.
    - Harel praises the addition and mentions that it helps visualize dependencies and governance, making it easier to answer use cases visually. Maciej adds that the complete events feature allows users to know when a spark drop ended.
    - Michael Collado asks about how well the feature works in the data bricks environment, which Maciej acknowledges as a great question and mentions that they need to try it more in data bricks, as it is always slightly different from the standard.
    - Maciej explained that they wanted to have a streaming integration with Pink, which is currently the most popular streaming system. They had an idea to make a Pink integration, but the code they copied from the integration was not very beautiful and had a lot of reflection and instance checking.
    - They decided to create a workaround to get as much value as they can and propose an interface that allows them to create a better integration. They had other things to do in the meantime, but then they discovered that a support customize job was created by Dance, which introduced several interfaces.
    - They realized that the perfect interface was already created, but it had only one piece of information. The problem was that the IP had already passed, and the listener would have to know every connector Emerson to get information from it, which is impossible.
    - Maciej explains the limitations of open source connectors and how it affects their integration process. They have resolved this issue by adding a data set interface to make connectors implement it and make the lineage vertex implement the list of data sets that they actually attach.
    - This breaks the capping between the collector and listener because they both are bigger face that basically doesn't change and changes. It takes only forward compatible.
    - The end result is that they have an interfacing thing that is open lineage but not quite named open lineage. This solution is easier to convince the community to create an interface, that there's concerns is done to be find like on a library that the third part and they can have a clear one to one mapping without breaking anything.
    - Maciej asks if there are any questions.
    - Michael Robinson thanks Maciej for his contribution and acknowledges that he joined the call after work hours. Julien also thanks Maciej for coordinating with the link commuters on this great collaboration.
    - Eric offers to give a general update at the end of the call.

Open Discussion
    - Michael Robinson moves on to open discussion and asks if anyone has any discussion items.

Update on Spark Integration
    - Damien shared his experience with the scalar two point 13 support to Apache Spark integration. They deployed the open line spark integration into their own internal pipelines and it worked well.
    - However, when they moved to new clusters running different versions of scalar, the jobs failed due to conflicting scalar major versions. The reason for this is that when Java code is compiled, the compiler injects the full class names or full type signature of a method, which includes what its return type is and what its input ran types are.
    - When calling a method in Apache Spark, if the same method has two different types signatures, the JVM throws a runtime error. The solution to this is to compile the entire application for an entire project against the Apache Spark libraries.
    - Damien explains how to configure the app to consume relevant jars and run integration tests for different versions of Spark, with the exception of Spark 2.4 which only uses Scala 2.12. Maciej thanks Damien for his contribution and expresses a desire for faster reviews.
    - Michael Robinson congratulates Damien on becoming a committer and thanks him for his contributions. Eric provides a general update on interest in airflow and spark integrations, with a focus on enterprise adoption and versioning conflicts.
    - They plan to release a Dag instead of a plugin to help with configurations. Michael Robinson concludes the call and announces the next meeting.

Outline

Announcements and events
    - Michael outlines the agenda for the meeting, including announcements, recent releases, updates on Airflow provider and Spark integration, and discussion items.
    - Michael announces upcoming events, including the publication of the annual ecosystem survey results, a meetup in London on January 31st, and a talk at Kafka Summit in March.
    - Alex asks if the meetup will be online as well, and Michael clarifies that it will be in person only.

Release updates
    - Michael Robinson informs the participants about the recent release of version 1.7.0 and mentions an important compatibility notice regarding the airflow integration. He encourages the use of their official open lineage airflow provider and explains that the transition is easy and straightforward.
    - He also mentions the addition of the parent run facet to all events in the airflow integration and the removal of support for airflow two. Michael thanks all contributors, including Koch Bermuda, who provided fixes for the release.

Spark job hierarchy
    - Michael Robinson plays a recorded update from Maciej, who provides important updates on the provider and ongoing discussions of possible improvements to job hierarchy schematics in the spark integration. Julien acknowledges the recording, and Maciej provides updates on recent changes to the Airflow Provider.
    - He mentions the addition of support for multiple GCS industry-related operators and bug fixes.
    - He proposes having more granular event semantics and consensus on having a single parent run for all actions.
    - Inputs and outputs of the job hierarchy for spark and the need for more information about how they are related are discussed. They mention the open lineage feature called "parent" that allows specifying that a run was scheduled by something else or is a sub-run.
    - They agree on having a single parent run that contains all actions but note that it is still being discussed.
    - Maciej explains how the application run and parent run work, allowing customers to correlate jobs and understand execution. He mentions the power it gives to consumers who want to display aggregate data and make sure users understand how jobs look like.
    - Maciej shares links to issue #1672 and the PyPI doc and download for the Airflow Provider, encouraging questions or contributions to the ongoing discussion.

Simplify jump a key
    - Michael invites discussion on topic #1672 and asks if anyone wants to add a topic. Jens brings up the simplify jump a key for spark issue and suggests having a quick discussion on it.
    - Julien explains that the explanation they just saw was recorded because Maciej couldn't join the meeting. Jens realizes his check is not there and will discuss it with Maciej separately.
    - Michael asks if there are any other items for discussion.

Registry proposal
    - Julien updates the registry proposal and shares his screen to show the recent updates, including clarification for consumers to independently discover and support custom facet opening, acceptance guidelines for claiming a name and entity, and examples of how to use them. He believes it's close enough to implement the first version and see where they're going.
    - Julien reviewed the recording of a meeting and integrated feedback. The core facets will be moved in the registry under the core name and follow the same rules as all other custom facets.
    - Examples for each facet will be moved to the registry as well, ensuring consistency and validation. Additional metadata is available to show documentation on use cases.
    - The first version of the registry will be managed and improved over time. Jens asked about the format for spec versions, which could be extended.
    - Michael Robinson expressed happiness with the progress and thanked Sheeri for driving the conversation.
    - Jens asked about the format for spec versions and Julien explained that it's currently exact only but could be extended. He suggested tagging Sheeri to discuss further on the extension of these versions.

Learning since last call
    - Eric shared some learning since the last call.
    - Eric reports growing demand and adoption of OpenLineage, with no hesitancy from organizations due to its perceived business value. He mentions the need for better documentation to accelerate adoption and optimize for speed in two areas: proper versions of everything in place and diagnosing if there are needs that the community needs to build out for support.
    - Eric suggests an Airflow plugin to provide a report on misconfigurations and help stakeholders understand the details. He also mentions the need for access to the boundary or threshold of support to get organizations up and running and showing business value.
    - Michael Robinson asks Eric about a specific document that would be helpful for version requirements and coverage information. Eric explains that the plugin they developed will identify things that need to be done to press forward for the organization implementing the lineage.
    - He gives an example of an organization using AWS Glue and how they had to throw on the brakes because they didn't have knowledge of the community's investment in building up support where it's needed. Eric puts out a problem statement about the need for all the folks adjacent to the core community to know the boundary or threshold of support to get organizations implemented and up and running.
    - Michael Robinson and Julien acknowledge the information.

Column lineage in Spark
    - Eric explains that they have been reaching out to the community for information about coverage, but having it in one place would be helpful. He encourages opening issues and shares that a new resource on the subject is available.
    - Julien agrees.
    - Michael Robinson asks if anyone else has similar experiences.
    - Eric asks if anyone else has experienced the same.
    - Jens confirms that he understands the question and suggests having the information in a single place would be helpful.
    - Eric thanks Jens.
    - Michael Robinson shares a new resource on the subject and encourages opening issues. He asks Eric about plans for a plugin.
    - Eric was looking at the repo and asks Michael to repeat the question. Michael asks about plans for the plugin.
    - Eric suggests following up in the community slack and promises to contribute.
    - Michael Robinson acknowledges Eric's contribution.

Integration matrix
    - Jens suggests expanding on the integration matrix and mentions issues with iceberg support in Spark.
    - Eric reflects on Jens' suggestion.
    - Michael Robinson thanks Jens for the input.

Outline

    - Michael Robinson from Astronomer welcomes everyone and goes through the agenda, which includes brief announcements, a release update, metrics on community growth, an update on dataset support in Spark, and open discussion items. He also reminds participants about the ecosystem survey and announces an upcoming meetup in London co-hosted with Confluence.
    - He shares the success of a recent event in Warsaw and thanks contributors and attendees.
    - Michael Robinson provides details on the recent release (1.6.2) which includes support for version 1.5, metadata sending without running a dbt command, and improvements to job listeners and lineage in Flink and Spark. He also mentions bug fixes and contributions from new contributors.
    - He shares exciting news about streaming job support in Marks project and expects a larger release soon.
    - Michael Robinson moves on to share some metrics on momentum and new partners added in the last year, including Google Cloud, Grai, and Metaphor. He directs participants to GitHub and the revamped ecosystem page at OpenLineage for more details.

Metrics on Community Growth
    - Michael Robinson shares insights from the lfai and data dashboards, showing increases in total and active contributors as well as commits.
    - Harel shared that there may be an issue with the way commits are being counted, but the general trend of 5,000+ commits per month is accurate. He also shared details about their global community membership and contributors using the Orbit tool.

New Job Facet: "Job Type"
    - Pawel Leszczynski presented a new job facet called "job type" which contains information about processing type, integration, and pricing on the query command. This job type is used for streaming jobs and is already being implemented in their Link integration.
    - Harel thanked him for the presentation.
    - Harel expressed excitement about seeing events stream into Marquez and Pawel shared that they are able to merge the PR, but there are still some issues with CI.

Open Proposals Discussion
    - Harel expressed excitement for an upcoming release and suggested that encouraging messages on Marquez might help. The next item on the agenda is discussing open proposals.
    - Jens discusses two proposals related to the column level line asset, which have been discussed with Aba. He explains the current state of the column level line and its issues, including the lack of a clear contract between producers and consumers regarding transformation types.
    - The first proposal is to create a taxonomy of types to address this issue. The second proposal addresses situations where the transformation type would be different for a given pair of input field and output field.
    - Jens presents a document with more details on transformation types for column level lines, which should be complete, disjunct, unambiguous, and optional. He also proposes adding a transformation sub-type for more extension.
    - Jens proposes adding a subtype and a separate field for masked transformation, creating a transformation object, and moving the fields related to transformation into their own object. Papa suggests adding a masked field to allow users to send information if they wish to.
    - Harel asks about adding the name of the masking function as its own property, and Mandy suggests it could be a free form name or an extra property for masking algorithm. They agree to swap the masked field into the name of the mask, and recognize that masking can mean different things in different use cases.
    - They discuss the possibility of coalescing on some naming convention or using reference data management to control values.
    - Jens asks Mandy to check the GitHub issue with the proposal and provides the slide number. Harel links both proposals in the chat.
    - Mandy thanks Harel for doing the proposal.
    - Harel expresses gratitude for the proposals and invites others to open a proposal on the project. The next item on the agenda is discussion, but there are no items for this month.

Reviewing New Core Facets
    - Jens asks about the process for reviewing new core facets and suggests discussing them before they get merged. Pawelleszczynski explains the process of creating a JSON file and creating a PR, and suggests waiting a few weeks for others to review the proposal.
    - Jens agrees and suggests highlighting spec changes more frequently.
    - Pawel suggests asking Julien for review and acknowledges that it may take longer during Christmas time. Harel emphasizes the responsibility of the community to each other and suggests allowing for more duration before merging and releasing.
    - Eric presents another item on the agenda.
    - Harel thanks everyone for their input and moves on to the next item on the agenda.

Adoption of Alina
    - Eric shares details on adoption of Atlan supporting different flavors of implementation and how brands adopting OpenLineage speak to the momentum of the community building. He thanks all committers for backing something that's making a difference in the data ecosystem.
    - Harel echoes Eric's words and appreciates everyone who contributed over the past few years, making this project an industry standard. He thanks all contributors and adopters like admin, Google, and everyone else on the call and in the ecosystem.

Migration from standalone Open Lineage package to Airflow provider
    - Jakub explained how to migrate from the standalone openly the flow package to the airflow provider. He gave reasons why they wanted to become an airflow provider, including making sure that the metadata collected in airflow is not breaking airflow itself.
    - They also keep the latest code up to date with all the providers and become part of these providers of the operators. There were a couple of changes introduced in the provider package, and the main question is how to migrate.
    - The simplest way is to just do the install for the specific package. One of the things they would like to walk away from this customer structures, and there was and still is a possibility to write a customer structure that was controlled by the open infrastructures environment variable.
    - Jakub explains that if a user has implemented some get open age assets method previously based on the old module and class, they do not need to worry about it because it is translated. However, if they install opening flow, they will fail to import the old class and need to change the import path.
    - There are changes introducing configuration, and there is a whole section called open image in conflict. Many of the features that were previously available in opening package are also compatible with the provider.
    - People usually like open in URL, which is pretty common and still works. But some entries in the open in age section take precedence over what's been previously handled by environment variables.
    - Jakub gives examples of how the logic for like conflict takes precedence over open in URL. He mentions that the documentation has more information on how it works.
    - He also explains how to add new integration in the provider or other providers that make use of opening provider. They want to give up on using open in age common data set module and use just the classes from the open in age python client.
    - Jakub gives quick advice on how to grab some information from execution of the operator. Previously, when they didn't have any control or influence on how to grab some information from execution of the operator, they needed to read the code and see that maybe job ID is returned as an ex come.
    - Now when they added the integration in the query operator itself, they can just change the code so it saves the job ideas and attributes.
    - Jakub gives a quick demo of how it works. He is using breeze, which is a mostly development environment and cli for airflow.
    - He is using on two point seven point one and is also using integration open in age, which instant Marcus also that's an option that they have in their flow. The only package that he is using is posts because he'll be using or provider.
    - He shows how it works and mentions that the beauty of e-mail life is that he doesn't know if it should work.
    - Jakub says that it should work in a minute.
    - Jakub types in his password.
    - Jakub says that he doesn't need to run post scripts, but actually he doesn't have just to prove he doesn't have any.
    - Jakub says that it's working. He is running some example that uses focus as back end.
    - Jakub says that previously, there was nothing to configure more if a user has like opening the CR.
    - Jakub explains that he changed the next piece and this is development, but the name is changed because he hasn't experimented with something. Eventually, the events came to market.
    - Jakub tries it again.
    - Jakub demonstrates a quick demo of three options for package installation and rerunning history. Julien thanks Jakub and asks if there are any questions about migration from the old open age integration into the new airflow provider.

Observability for Open Lineage OpenLineage markers
    - Julien introduces the discussion topic of observability for opening age markers and invites Harel to start. Harel asks the audience about ensuring liability of lineage collection and what kind of operability they would like to see, such as distributed tracing.
    - He suggests gathering feedback on a slack channel. Julien thinks the metrics added to the airflow integration by Harel are a good starting point for observability.
    - Hloomba mentions enabling retention policy on all environments and suggests observability on database retention to help with memory or CPU performance. Harel suggests enabling metrics out of the box and instrumenting more functions using drop wizard as a web server.
    - Julien and William discuss having metrics on the retention job to track how the data retention job keeps the database small.
    - Jeevan asked about the possibility of having an open lineage event for Spark applications, and Pawelleszczynski explained the need for a parent run faster to identify each Spark action as part of a bigger entity, the Spark application. Jens suggested having unique job names for Spark actions and the parent Spark application.
    - Pawelleszczynski explained that the current job name is constructed based on the name of the operator or Spark logical note and appended with a dataset name, but they can make it optional to have a human-readable job name or use a hash on the logical plan to ensure uniqueness.
    - Harel mentioned having good news for Bob and suggested discussing it next week.
    - Jens added that having unique job names would help distinguish each Spark action and its runs, and Pawelleszczynski explained the current job naming convention and the possibility of making it unique using a hash on the logical plan.
    - Julien asked if anyone had more comments on the topic.

  • Thanks to all the contributors, including new contributor @versaurabh!
  • More details: https://github.com/OpenLineage/OpenLineage/blob/main/CHANGELOG.md
• Column-level lineage update [Maciej]
  • What is the OpenLineage SQL parser?
    • At its core, it’s a Rust library that parses SQL statements and extracts lineage data from it 
    • 80/20 solution - we’ll not be able to parse all possible SQL statements - each database has custom extensions and different syntax, so we focus on standard SQL.
    • Good example of complicated extension: Snowflake COPY INTO https://docs.snowflake.com/en/sql-reference/sql/copy-into-table.html
    • We primarily use the parser in Airflow integration and Great Expectations integration
    • Why? Airflow does not “understand” a lot of what some operators do, for example PostgreSqlOperator
    • We also have Java support package for parser   
  • What changed previously?
    • Parser in current release can emit column-level lineage!
    • Last OL meeting Piotr Wojtczak, primary author of this change presented new core of parser that enabled that functionality
      https://www.youtube.com/watch?v=Lv_bODeAVYQ
    • Still, the fact that Rust code can do that does not mean we have it for free everywhere
  • What has changed recently?
    • We wrote “glue code” that allows us to use new parser constructs in Airflow integration
    • Error handling just got way easier: SQL parser can “partially” parse SQL construct, and report errors it encountered, with particular statements that caused it.
  • Usage
    • Airflow integration extractors based on SqlExtractor (ex. PostgreSqlExtractor, SnowflakeExtractor, TrinoExtractor…) are now able to extract column-level lineage
    • Close future: Spark will be able to extract lineage from JDBCRelation.
• Recent improvements to the Airflow integration [Kuba]
  • OpenLineage facets
    • Facets are pieces of metadata that can be attached to the core entities: run, job or dataset
    • Facets provide context to OpenLineage events
    • They can be defined as either part of the OpenLineage spec or custom facets
  • Airflow generic facet
    • Previously multiple custom facets with no standard
      • AirflowVersionRunFacet as an example of rapidly growing facet with version unrelated information
    • Introduced AirflowRunFacet with Task, DAG, TaskInstance and DagRun properties
    • Old facets are going to be deprecated soon. Currently both old and new facets are emitted
      • AirflowRunArgsRunFacet, AirflowVersionRunFacet, AirflowMappedTaskRunFacet will be removed
      • All information from above is moved to AirflowRunFacet
  • Other improvements (added in 0.19.2)
    • SQL extractors now send column-level lineage metadata

    • Further facets standardization

      • Introduced ProcessingEngineRunFacet
        • provides processing engine information, e.g. Airflow or Spark version
      • Improved support for nominal start & end times
        • makes use of data interval (introduced in Airflow 2.x)
        • nominal end time now matches next schedule time
      • DAG owner added to OwnershipJobFacet
      • Added support for S3FileTransformOperator and TrinoOperator (@sekikn’s great contribution)
• Discussion: what does it mean to implement the spec? [Sheeri]
  
  • What is it mean to meet the spec?
    • 100% compliance is not required
    • OL ecosystem page
      • doesn't say what exactly it does
      • operational lineage not well defined
      • what does a payload look like? hard to find this info
    • Compatibility between producers/consumers is unclear
  • Important if standard is to be adopted widely [Mandy]
    • Egeria: uses compliance test with reports and badging; clarifies compatibility
    • test and test cases available in the Egeria repo, including profiles and clear rules about compliant ways to support Egeria
    • a badly behaving producer or consumer will create problems
    • have to be able to trust what you get
  • What about consumers? [Mike C.]
    • can we determine if they have done the correct thing with facets? [John]
    • what do we call "compliant"?
    • custom facets shouldn't be subject to this – they are by definition custom (and private) [Maciej]
    • only complete events (not start events) should be required – start events not desired outside of operational use cases [Maciej]
  • There's a simple baseline on the one hand and facets on the other [Julien]
  • Note: perfection isn't the goal
    • instead: shared test cases, data such as sample schema that can be tested against
  • Marquez doesn't explain which facets it's using or how [Willy]
    • communication by consumers could be better
  • Effort at documenting this: matrix [Julien]
  • How would we define failing tests? [Maciej]
    • at a minimum we could have a validation mode [Julien]
    • challenge: the spec is always moving, growing [Maciej]
    • ex: in the case of JSON schema validation, facets are versioned individually but there's a reference schema that is versioned that might not be the current schema. Facets can be dereferenced, but the right way to do this is not clear [Danny]
    • one solution could be to split out base times, or we could add a tool that would force us to clean this up
    • client-side proxy presents same problem; tried different validators in Go; a workaround is to validate against the main doc first; by continually validating against the client proxy we can make sure it stays compliant with the spec [Minkyu]
    • Mandy: if Marquez says it's "OK," it's OK; we've been doing it manually [Mandy]
    • Marquez doesn't do any validation for consumers [Mike C.]
    • manual validation is not good enough [Mandy]
    • I like the idea of compliance badges – it would be cool if we had a way to validate consumers and there were a way to prove this and if we could extend validation to integrations like the Airflow integration [Mike C.]
  • Let's follow up on Slack and use the notes from this discussion to collaborate on a proposal [Julien]

2022

December 8, 2022 (10am PT)

...

• Announcements [Julien]

  • Added

    • Airflow: add dag_run information to Airflow version run facet #1133 @fm100
      Adds the Airflow DAG run ID to the taskInfo facet, making this additional information available to the integration.
    • Airflow: add LoggingMixin to extractors #1149 @JDarDagran
      Adds a LoggingMixin class to the custom extractor to make the output consistent with general Airflow and OpenLineage logging settings.
    • Airflow: add default extractor #1162 @mobuchowski
      Adds a DefaultExtractor to support the default implementation of OpenLineage for external operators without the need for custom extractors.
    • Airflow: add on_complete argument in DefaultExtractor #1188 @JDarDagran
      Adds support for running another method on extract_on_complete.
    • SQL: reorganize the library into multiple packages #1167 @StarostaGit @mobuchowski

• Implementing OpenLineage proposal and discussion [Julien]
  • Procedure for implementing OpenLineage is under-documented
  • Goal: provide a better guide on the multiple approaches that exist
  • Contributions are welcome
  • Expect more information about this at the next meeting
• MANTA integration update [Petr]
  • Project: MANTA OpenLineage Connector
  • Straightforward solution:
    • Agent installed on customer side to setup an API endpoint for MANTA
    • MANTA Agent will hand over OpenLineage events to the MANTA OpenLineage Extractor, which will save the data in a MANTA OpenLineage Event Repository
    • Use the MANTA Admin UI to run/schedule the MANTA OpenLineage Reader to generator an OpenLineage Graph and produce the final MANTA Graph using a MANTA OpenLineage Generator
    • The whole process will be parameterized
  • Demo:
    • Example dataset produced by Keboola integration
    • All dependencies visualized in UI
    • Some information about columns is available, but not true column lineage
    • Possible to draw lineage across range of tools
  • Looking for volunteers willing to test the integration
  • Q&A
    • Are you using the Column-level Lineage Facet from OpenLineage?
      • Not yet, but we would like to test it
      • Find a good example of this in the OpenLineage/workshops/Spark GitHub repo
      • What would be great would be a real example/real environment for testing
• Linking CMF (a common ML metadata framework) and OpenLineage [Suparna & Ann Mary]
  • https://github.com/HewlettPackard/cmf

    • linkage needed between forms of metadata for conducting AI experiments
    • concept: "git for AI metadata" consumable by tools such as Marquez and Egeria after publication by an OpenLineage-CMF publisher
    • challenges:
      • multiple stages with interlinked dependencies
      • executing asynchronously
      • data centricity requires artifact lineage and tracking influence of different artifacts and data slices on model performance
      • pipelines should be Reproducible, Auditable and Traceable
      • end-to-end visibility is necessary to identify biases, etc.
    • AI for Science example:
      • training loop in complex pipeline with multiple models optimized concurrently
        • e.g., an embedding model, edge selection model and graph neural model in same pipeline
        • CMF used to capture metadata across pipeline stages
    • Manufacturing quality monitoring pipeline
      • iterative retraining with new samples added to the dataset every iteration
      • CMF tracks lineage across training and deployment stages

    • an Airflow pipeline processes queries against Snowflake
    • separate job: pulls access history and assembles lineage metadata
    • two angles: Airflow sees it, Snowflake records it
  • the meat of the integration: a view that does untold SQL madness to emit JSON to send to OL
  • result: you can study the transformation by asking Snowflake AND Airflow about it
  • required: having access history enabled in your Snowflake account (which requires special access level)
  • Q & A
    • Howard: is the access history task part of the DAG?
    • Ross: yes, there's a separate DAG that pulls the view and emits the events
    • Howard: what's the scope of the metadata?
    • Ross: the account level
    • Michael C: in Airflow integration, there's a parent/child relationship; is this captured?
    • Ross: there are 2 jobs/runs, and there's work ongoing to emit metadata from Airflow (task name)

    • Julien: lineage endpoint for col-level lineage to layer on top of what already exists
    • Willy: this makes sense – we could use the method for input and output datasets as a model
    • Michael C.: I don't know that we need to add an endpoint – we could augment the existing one to do something with the data

• New committers [Julien]
  • 4 new committers were voted in last week
  • We had fallen behind
  • Congratulations to all
• Release overview (0.6.0-0.6.1) [Michael R.]
  • Added
    • Extract source code of PythonOperator code similar to SQL facet @mobuchowski (0.6.0)
    • Airflow: extract source code from BashOperator @mobuchowski (0.6.0)
      • These first two additions are similar to SQL facet
      • Offer the ability to see top-level code
    • Add DatasetLifecycleStateDatasetFacet to spec @pawel-big-lebowski (0.6.0)
      • Captures when someone is conducting dataset operations (overwrite, create, etc.)
    • Add generic facet to collect environmental properties (EnvironmentFacet) @harishsune (0.6.0)
      • Collects environment variables
      • Depends on Databricks runtime but can be reused in other environments
    • OpenLineage sensor for OpenLineage-Dagster integration @dalinkim (0.6.0)
      • The first iteration of the Dagster integration to get lineage from Dagster
    • Java-client: make generator generate enums as well @pawel-big-lebowski (0.6.0)
      • Small addition to Java client feat. better types; was string
  • Fixed
    • Airflow: increase import timeout in tests, fix exit from integration @mobuchowski (0.6.0)
      • The former was a particular issue with the Great Expectations integration
  • • Reduce logging level for import errors to info @rossturk (0.6.0)
      • Airflow users were seeing warnings about missing packages if they weren't using a part of an integration
      • This fix reduced the level to Info
    • Remove AWS secret keys and extraneous Snowflake parameters from connection URI @collado-mike (0.6.0)
      • Parses Snowflake connection URIs to exclude some parameters that broke lineage or posed security concerns (e.g., login data)
      • Some keys are Snowflake-specific, but more can be added from other data sources
    • Convert to LifecycleStateChangeDatasetFacet @pawel-big-lebowski (0.6.0)
      • Mandates the LifecycleStateChange facet from the global spec rather than the custom tableStateChange facet used in the past
    • Catch possible failures when emitting events and log them @mobuchowski (0.6.1)
      • Previously when an OL event failed to emit, this could break an integration
      • This fix catches possible failures and logs them
• Process for blog posts [Ross]
  • Moving the process to Github Issues

  • Follow release tracker there

  • Go to https://github.com/OpenLineage/website/tree/main/contents/blog to create posts

  • No one will have a monopoly

  • Proposals for blog posts also welcome and we can support your efforts with outlines, feedback

  • Throw your ideas on the issue tracker on Github

• Retrospective: Spark integration [Willy et al.]

  • Willy: originally this part of Marquez – the inspiration behind OL

    • OL was prototyped in Marquez with a few integrations, one of which was Spark (other: Airflow)

    • Donated the integration to OL

  • Srikanth: #559 very helpful to Azure

  • Pawel: is anything missing from the Spark integration? E.g., column-level lineage?

  • Will: yes to column-level; also, delta tables are an issue due to complexity; Spark 3.2 support also welcome

  • Maciej: should be more active about tracking projects we have integrations with; add to test matrix 

  • Julien: let’s open some issues to address these

• Open Discussion
  • Flink updates? [Julien]

    • Maciej: initial exploration is done

      • challenge: Flink has 4 APIs

      • prioritizing Kafka lineage currently because most jobs are writing to/from Kafka

      • track this on Github milestones, contribute, ask questions there

    • Will: can you share thoughts on the data model? How would this show up in MZ? How often are you emitting lineage? 

    • Maciej: trying to model entire Flink run as one event

    • Srikanth: proposed two separate streams, one for data updates and one for metadata

    • Julien: do we have an issue on this topic in the repo?

    • Michael C.: only a general proposal doc, not one on the overall strategy; this worth a proposal doc

    • Julien: see notes for ticket number; MC will create the ticket

      • https://github.com/OpenLineage/OpenLineage/issues/596

    • Srikanth: we can collaborate offline

• Dagster integration demo [Dalin]
  • Initiated by Dalin Kim
  • OL used with Dagster on orchestration layer
  • Utilizes Dagster sensor
  • Introduces OL sensor that can be added to Dagster repo definition
  • Uses cursor to keep track of ID
  • Looking for feedback after review complete
  • Discussion:
    • Dalin: needed: way to interpret Dagster asset for OL
    • Julien: common code from Great Expectations/Dagster integrations
    • Michael C: do you pass parent run ID in child job when sending the job to MZ?
    • Hierarchy can be extended indefinitely – parent/child relationship can be modeled
    • Maciej: the sensor kept failing – does this mean the events persisted despite being down?
    • Dalin: yes - the sensor’s cursor is tracked, so even if repo goes down it should be able to pick up from last cursor
    • Dalin: hoping for more feedback
    • Julien: slides will be posted on slack channel, also tickets
• Open discussion
  • Will: how is OL ensuring consistency of datasets across integrations? 
  • Julien: (jokingly) Read the docs! Naming conventions for datasets can be found there
  • Julien: need for tutorial on creating integrations
  • Srikanth: have done some of this work in Atlas
  • Kevin: are there libraries on the horizon to play this role? (Julien: yes)
  • Srikanth: it would be good to have model spec to provide enforceable standard
  • Julien: agreed; currently models are based on the JSON schema spec
  • Julien: contributions welcome; opening a ticket about this makes sense
  • Will: Flink integration: MZ focused on batch jobs
  • Julien: we want to make sure we need to add checkpointing
  • Julien: there will be discussion in OLMZ communities about this
  • In MZ, there are questions about what counts as a version or not
  • Julien: a consistent model is needed
  • Julien: one solution being looked into is Arrow
  • Julien: everyone should feel welcome to propose agenda items (even old projects)
  • Srikanth: who are you working with on the Flink comms side? Will get back to you.

  • Notes: 

    Mission statement:

    • https://github.com/OpenLineage/OpenLineage/issues/84

    • Overall consensus on the statement.

    • TODO: vote by commenting on the ticket

    Spec versioning mechanism:

    • The goal is to commit to compatible changes once 0.1 is published

    • We need a follow up to separate core facet versioning

    
    => TODO: create a separate github ticket.

    • The lineage event should have a field that identifies what version of the spec it was produced with

    • => TODO: create a github issue for this

    • TODO: Add issue to document version number semantics (SCHEMAVER)

    Extend Event State notion:

    • where do we capture more precise state transitions like RESTART?

    • Discussion should happen here: https://github.com/OpenLineage/OpenLineage/issues/9

    OpenLineage 0.1:

    • finalize a few spec details for 0.1 : a few items left to discuss.

    • In particular job naming

    • parent job model

    • Importing Marquez integrations in OpenLineage

    Open Discussion:

    • connecting the consumer and producer

      • TODO: ticket to track distribution mechanism

      • options:

        • Would we need a consumption client to make it easy for consumers to get events from Kafka for example?

        • OpenLineage provides client libraries to serialize/deserialize events as well as sending them.

      • proxy similar to OpenTelemetry Collector.

      • Send to Kafka: https://github.com/OpenLineage/OpenLineage/issues/70

      • We can have documentation on how to send to backends that are not Marquez using HTTP and existing gateway mechanism to queues.

    • Do we have a mutual third party or the client know where to send?

    • Source code location finalization

    • job naming convention

      • you don't always have a nested execution

      • can call a parent

    • parent job

    • You can have a job calling another one.

    • always distinguish a job and its run

    • need a separate notion for job dependencies

    • need to capture event driven: TODO: create ticket.

    
    TODO(Julien): update job naming ticket to have the discussion.
