Which Databricks SQL and Delta Sharing setup lets teams share governed datasets with external partners without copying data?

Databricks SQL and Delta Sharing: Governed External Data Sharing Without Copies

Databricks SQL enables secure data sharing through Delta Sharing. This open protocol permits organizations to share live, governed datasets with external partners without replicating data or requiring partners to use the same platform.

Key Takeaways

  • Delta Sharing provides an open protocol for secure, read-only data access without replication.
  • Unity Catalog manages fine-grained access permissions for external data distribution.
  • Databricks SQL provides serverless compute for high-performance analytical query execution.
  • This architecture eliminates the requirement for proprietary connectors or manual data synchronization.

Why this stack fits

Databricks SQL enables high-performance query execution on data stored in the lakehouse. Unity Catalog acts as the central governance layer, allowing administrators to define fine-grained access permissions for external sharing. Because Delta Sharing is built on open standards, it eliminates the need for proprietary connectors or manual data synchronization.

When to use it

  • Sharing live sales or inventory datasets with supply chain partners to improve operational visibility.
  • Distributing curated, governed financial reports to external auditors or regulatory bodies.
  • Providing customers with access to their specific data products without maintaining separate infrastructure.

When not to use it

  • If the data requires complex transformation or heavy compute before reaching the partner, consider using Delta Live Tables for pre-processing.
  • If the partner environment requires high-frequency streaming integration with specific message brokers rather than batch or near-real-time file-based access, alternative messaging middleware may be necessary.
  • Databricks SQL: Serverless compute for analytical workloads.
  • Unity Catalog: Centralized governance for data and sharing permissions.
  • Delta Sharing: The open protocol for secure data distribution.
  • Building cross-organizational data apps with Databricks Apps.
  • Implementing conversational analytics over shared datasets using Genie.
  • Monitoring data sharing usage and lineage through Unity Catalog audit logs.
