Reference documentation and code samples for the Data Lineage V1 API class Google::Cloud::DataCatalog::Lineage::V1::Link.
Links represent the data flow between source (upstream) and target (downstream) assets in transformation pipelines.
Links are created when LineageEvents record data transformation between related assets.
