Data Lineage

Visualize data flow from source to destination and analyze the impact of changes.

Overview

Lineage tracks how data moves through FacilFlow — from source systems, through pipelines and transformations, to sinks and dashboards. The lineage graph is built automatically as pipelines run.

Lineage Graph

Navigate to Analyze > Lineage to view the graph.

The graph is rendered with React Flow and shows:

• Nodes: Data sources, pipelines, transformations, sinks, dashboards
• Edges: Data flow direction between nodes

Navigation

• Pan by dragging the canvas
• Zoom with scroll wheel
• Click a node to see details
• Use the minimap for orientation in large graphs

Upstream / Downstream

Select any node to see:

• Upstream: All sources and transformations that feed into this node
• Downstream: All consumers that depend on this node’s output

Upstream and downstream paths are highlighted on the graph.

Pipeline Lineage

Each pipeline automatically captures lineage as it runs:

• Source nodes register their origin systems
• Processor nodes record transformations applied
• Sink nodes register the destination

This happens without manual configuration. Open any pipeline and click Lineage to see its data flow.

Impact Analysis

Before modifying a data source or pipeline, check what will be affected:

1. Select the node you plan to change
2. Click Impact Analysis
3. View all downstream dependencies — pipelines, dashboards, quality rules, and consumers
4. Assess risk before making changes

Impact analysis helps prevent breaking downstream consumers when modifying schemas, pipelines, or data sources.
