DataHub

Zingle can optionally connect to DataHub to enrich its analysis with usage, lineage, and ownership signals. This is a read-only integration used to make Optimize scans and semantic analysis smarter.

Requirements​

  • A DataHub instance (self-hosted or managed).
  • The GMS GraphQL endpoint URL and an access token.

Access needed​

  • Read-only access to DataHub's GraphQL API. Zingle queries DataHub for signals; it does not write to DataHub.

What it enables​

  • Bring usage and lineage signals into Optimize scans and semantic analysis, so recommendations account for how assets are actually used and how they connect downstream.
  • Incorporate ownership and downstream-dashboard context reported by DataHub.

What it can't do​

  • Zingle does not write to or modify DataHub.
  • DataHub is optional - Zingle works without it; connecting it improves the quality of certain signals.

Common setup issues​

  • No signals appear. Verify the GMS GraphQL endpoint URL and token, and that the relevant assets are cataloged in DataHub.
  • Connection unauthorized. Re-check the access token and its permissions.
