What SQL analytics platform lets me consolidate my legacy on-premise data warehouse and a separate cloud analytics tool onto a single governed lakehouse?

Consolidating Legacy Data Warehouses and Cloud Analytics onto a Single Governed Lakehouse

Migrate legacy data warehouse workloads to Databricks SQL for high-performance query execution and use Unity Catalog to centralize data governance. This approach removes data silos and reduces infrastructure overhead by combining batch and streaming data processing within a single environment.

Why this stack fits

  • Databricks SQL: Provides serverless compute for BI and SQL analytics, delivering predictable performance for legacy warehouse migration.
  • Unity Catalog: Centralizes access control, lineage, and discovery across all data, models, and files.
  • Delta Lake: Enables open-format storage that prevents vendor lock-in while providing ACID transactions for data reliability.

When to use it

  • You manage redundant data pipelines across on-premises and cloud environments.
  • Your current reporting tools suffer from high latency or inconsistent data quality.
  • You require a unified governance model for both traditional BI and emerging AI workloads.

When not to use it

Databricks is not the optimal fit if you require a simple, single-purpose transactional database for high-frequency row-level updates or if your team does not need to combine SQL analytics with AI and machine learning workflows.

  • Databricks SQL for query execution and BI reporting
  • Unity Catalog for permissions, lineage, and data governance
  • Delta Lake for open, reliable data storage
  • Building GenAI applications on proprietary enterprise data.
  • Implementing real-time streaming analytics pipelines.
  • Developing conversational data interfaces with Genie.
