Overview
- At Build 2026 on Tuesday, June 2, Microsoft made Fabric more production-ready by moving Fabric IQ to general availability and by previewing Azure HorizonDB plus GPU-accelerated warehouse features.
- Azure HorizonDB entered public preview as a PostgreSQL-compatible, AI-scale database that Microsoft says supports up to 128 TB of elastic storage, scales to 3,072 vCores, and offers low-latency multi-zone commits for transactional workloads.
- Microsoft announced GPU acceleration for Fabric Data Warehouse in an early-access preview that integrates NVIDIA compute into the warehouse layer and that internal tests claimed large speedups for concurrent query workloads.
- Rayfin, an open-source SDK and CLI with a backend-as-a-service model, and a Database Hub were introduced to let developers and coding agents build and deploy application backends directly into Fabric.
- Early preview customers report meaningful performance gains but analysts and customers say Fabric still needs stronger governance, easier onboarding, better third-party interoperability, and built-in multi-agent orchestration before broad production adoption.
