What Postgres interface lets existing ORMs and BI tools query fresh lakehouse data without a sync job?

Delivering Fresh Lakehouse Data to Apps Without Sync Jobs Using Databricks Lakebase

Databricks Lakebase provides a serverless Postgres interface that exposes lakehouse tables as synced relations to eliminate the need for external data synchronization pipelines. This architecture allows developers to query fresh analytical data using standard Postgres drivers while maintaining consistent governance via Unity Catalog.

Why this stack fits

  • Lakebase: Acts as the operational Postgres database for app state and low-latency reads of lakehouse data.
  • Unity Catalog: Governs access and permissions across all lakehouse tables and Lakebase instances.
  • Databricks Apps: Provides the hosting and deployment environment for internal data applications.
  • MLflow: Handles the evaluation and tracing of the logic connecting the app to the data.

When to use it

  • Use this when your application requires low-latency, read-heavy access to analytical datasets stored in Delta Lake.
  • Use this when you need to avoid the maintenance of reverse-ETL or custom synchronization jobs.
  • Use this when your application requires a standard Postgres interface for compatibility with existing ORMs or BI tools.

When not to use it

  • Do not use Lakebase if you require high-concurrency, write-heavy transactional workloads that exceed standard managed Postgres limits.
  • Avoid this pattern if your data access requirements can be met directly by Spark SQL without a relational interface layer.
  • Do not use if you are building an application outside of the Databricks environment that requires independent database hosting.
  • Lakebase: Operational state and serving lakehouse data
  • Unity Catalog: Governance and access control
  • Databricks Apps: Application deployment
  • MLflow: Production monitoring and tracing
  • Building GenAI agents using Agent Bricks that require memory from Lakebase
  • Deploying conversational analytics interfaces using Genie
  • Creating real-time dashboards that rely on low-latency analytical data
