Cube
Connect Cube measures, dimensions, and joins to the warehouse tables and upstream pipelines they depend on.
Semantic Layers & BIWhy Cube matters
AI agents pick metrics, dimensions, and joins based on what the semantic layer tells them. When a Cube definition drifts from reality, every agent and consumer downstream silently degrades, delivering wrong answers with full confidence.
Typedef connects Cube to the full lineage chain so you can catch semantic drift before it reaches an agent, reconcile definitions across tools, and trace exactly which consumers are affected when business logic changes.
What Typedef unlocks
Metric-to-source lineage
Trace any Cube measure from its YAML definition through the warehouse table back to the raw source, so you can verify the data, not just the definition.
Semantic drift detection
Spot when an upstream schema change or business logic update invalidates a Cube definition before agents and dashboards start returning wrong answers.
Agent impact analysis
See which AI agents and automated consumers rely on a specific measure or dimension, so definition changes are scoped before they ship.
Cross-platform reconciliation
Surface where Cube definitions align with or contradict definitions in other semantic layers and BI tools, so every consumer works from the same truth.
