Architecture Overview of Microsoft Fabric SQL

To understand the power of Microsoft Fabric SQL Databases, it’s important to see how they fit within the broader Fabric architecture, an integrated analytics platform built around a unified data foundation: OneLake.

At the core of Fabric lies OneLake, a single, open, delta-based storage layer that unifies data across services and clouds. It supports connections from Azure, Amazon S3, and, soon, Google Cloud, ensuring flexibility without duplication. All Fabric workloads, including SQL, run directly on top of this storage layer.

Microsoft Fabric comprises seven key workloads, each tightly integrated into the platform:

• Data Factory – Orchestrates data ingestion pipelines across on-prem, cloud, and SaaS sources.
• Synapse Data Warehousing – Offers scalable, lake-centric warehousing.
• Synapse Data Engineering – Provides Apache Spark for building and maintaining big data pipelines.
• Synapse Data Science – Supports full-scale model development and deployment.
• Synapse Real-Time Analytics – Enables streaming data analysis from applications and devices.
• Power BI – Delivers intuitive dashboards and reports connected directly to Fabric SQL and other sources.
• Data Activator – Empowers business users with no-code observability and data-driven automation.

Fabric SQL sits at the intersection of transactions and analytics, leveraging the scalability of OneLake and the interoperability of delta format. With automatic data replication, Fabric SQL makes operational data available across other workloads, no ETL or sync jobs required.

A key advantage of this architecture is performance at scale. For example:

• Ingesting 750 million rows into a data warehouse clocked 258K+ records/sec throughput.
• A Lakehouse ingestion of 120 million rows hit 810K+ records/sec, showing Fabric's ability to handle real-time, high-volume scenarios efficiently.

The openness of OneLake means Fabric SQL can integrate with any tool that understands Delta format, making it future-ready and vendor-agnostic.
