Dataflows - Performance: Disable V-Order Compression

Description

1. 2026-06-06
   Feature Description We are continuing to expand the significant performance gains delivered by Dataflow Gen2 with a new set of targeted performance and latency improvements across the end-to-end experience. These enhancements focus on the most critical execution paths and user interactions further differentiating Dataflow Gen2 from previous dataflow generations and raising the bar for low-code data transformations in Microsoft Fabric.This round of improvements addresses performance holistically--spanning data movement authoring execution monitoring and downstream consumption--to deliver a faster more responsive and more predictable experience at scale.Key enhancements include:* Reduced metadata refresh latency improving responsiveness when working with schemas and downstream consumers* The ability to turn off Vertiparquet compression giving advanced users greater control over performance and cost trade-offs for specific workloadsTogether these enhancements further extend the performance advantages of Dataflow Gen2 compared to earlier dataflow implementations reducing latency across both runtime execution and day-to-day interactions. By streamlining the most common and time-sensitive operations Dataflow Gen2 continues to deliver faster refreshes smoother authoring and more predictable behavior as data volumes and usage scale.At the same time these improvements materially enhance the customer experience around low-code data transformations in Fabric. Faster feedback loops more responsive monitoring and greater control over execution characteristics make it easier for both business users and data engineers to design operate and reuse dataflows with confidence--reinforcing Dataflow Gen2 as a high-performance production-ready transformation layer within Microsoft Fabric. -> Dataflow Gen2 will introduce a new preview capability that allows customers to disable V-Order (VertiParquet) compression for supported workloads and destinations giving advanced users greater control over execution behavior performance characteristics and cost trade-offs.This capability is especially valuable for scenarios where write latency and refresh throughput are prioritized over downstream storage optimization. By disabling V-Order compression customers can reduce processing overhead during writes helping accelerate refresh performance for large or time-sensitive ingestion and transformation workloads.With this preview organizations can better tune Dataflow Gen2 execution to meet the specific needs of their architectures and pipelines while continuing to leverage the scalability and flexibility of Microsoft Fabric.
