Thank you!

Actually everything is working on a push basis in ODD now. ODD Platform implements ODD Specification (https://github.com/opendatadiscovery/opendatadiscovery-speci...) and all agents, custom scripts and integrations, Airflow/Spark listeners, etc are pushing metadata to specific ODD Platform's endpoint (https://github.com/opendatadiscovery/opendatadiscovery-speci...). ODD Collectors (agents) are pushing metadata on a configurable schedule.

ODD Specification is a standard for collecting and gathering such metadata, ETL included. We gather metadata for lineage on an entity level now, but we plan to expand this to the column-level lineage at the end 2022 — start 2023. Specification allows us to make the system open and it's really easy to write your own integration by taking a look in what format metadata needs to be injected in the Platform.

ODD Platform has its own OpenAPI specification (https://github.com/opendatadiscovery/odd-platform/tree/main/...) so that the already indexed and layered metadata could be extracted via platform's API.

Also, thank you for sharing links with us! I'm thrilled to take a look how BMW solved a problem of lineage gathering from Spark, that's something we are improving in our product right now.
