VDK Lineage
VDK Lineage plugin provides lineage data (input data -> job -> output data) information and send it to a pre-configured destination. The lineage data is send using OpenLineage standard
At POC level currently.
Currently, lineage data is collected
- For each data job run/execution both start and end events including the status of the job (failed/succeeded)
- For each execute query we collect input and output tables.
TODOs:
- Collect status of the SQL query (failed, succeeded)
- Create parent /child relationship between sql event and job run event to track them better (single job can have multiple queries)
- Non-SQL lineage (ingest, load data,etc)
- Extend support for all queries
- provide more information using facets – op id, job version,
- figure out how to visualize parent/child relationships in Marquez
- Explore openlineage.sqlparser instead of sqllineage library as alternative
Usage
pip install vdk-lineage
And it will start collecting lineage from job and sql queries.
To send data using openlineage specify VDK_OPENLINEAGE_URL. For example:
export VDK_OPENLINEAGE_URL=http://localhost:5002
vdk marquez-server --start
vdk run some-job
# check UI for lineage
# stopping the server will delete any lineage data.
vdk marquez-server --stop
