Change Summary
Depends on #153.
Implement basic column lineage handler in consumer.
There are 2 DTO classes:
ColumnLineageDTO
- describes tuple(operation, source_dataset, target_dataset)
.DatasetColumnRelationDTO
- describessource_column -> target_column (optional)
relations withinColumnLineageDTO
Extractor builds list of these
ColumnLineageDTO
for each operation, and then perform bulk insert. Table rows are immutable, usingON CONFLICT DO NOTHING
with few additional checks to reduce database IO.This lacks any tests, these should be added in next commits.
