Exploring: gold.customer_360 - Upstream and downstream dependencies
Track upstream sources and downstream consumers with configurable depth (1-10 levels). Multi-node type support for tables, columns, and pipelines.
Track column-level transformations with confidence scoring. Direct copy detection, transformation expressions, and batch lineage creation.
Automatic lineage from SQL with 13+ dialects: Spark, Databricks, PostgreSQL, BigQuery, Snowflake, Redshift, dbt, and more via sqlglot.
Analyze downstream impact with severity levels (low → critical). Configurable depth (3-20 levels), AI recommendations, and full analysis history.
Save point-in-time lineage views. Load, compare, and manage snapshots with metadata tracking. One-click save from canvas.
Lineage coverage metrics with status indicators. Stale lineage detection, missing lineage alerts, and hub table identification.
React Flow visualization with mini-map, animated edges, zoom controls. Custom nodes for tables, columns, and pipelines with status indicators.
Consume events from Airflow, Spark, dbt, Dagster, Flink. Emit to Marquez, DataHub, Atlan, Collibra, Purview, OpenMetadata.
Auto-detect lineage from pipeline canvas. Link lineage to source pipelines and runs with status visibility (active/paused/error).
Track exactly how each column is derived. Color-coded by transformation type.
