OpenLineage is a standard for metadata and lineage collection that is growing rapidly. Column-level lineage is one of its most anticipated features of the community that has been developed recently. In this talk, we: * show foundations for column lineage within OpenLineage standard, * provide real-life demo on how is it automatically extracted from Spark jobs, * describe and demo column lineage extraction from SQL queries, * show how the lineage can be consumed on Marquez backend. We aim to provide demos to focus on practical aspects of the column-level lineage which are interesting to data practitioners all over the world.
