fabric-data-factory-perf-remediatelisted

Diagnose and resolve Microsoft Fabric Data Factory pipeline performance issues. Use when pipelines are slow, copy activities timeout, dataflows stall, activities are stuck, throughput is low, capacity is throttled, or jobs queue indefinitely. Covers copy activity tuning (parallelCopies, DIU, ITO, partitioning), pipeline monitoring via Monitoring Hub and workspace monitoring, Spark job queueing, capacity SKU limits, error code resolution, and dataflow optimization. Keywords include Fabric pipeline slow, copy activity performance, Data Factory throttling, pipeline timeout, activity stuck, TooManyRequestsForCapacity, HTTP 430, pipeline troubleshoot, dataflow performance, copy parallelism, intelligent throughput optimization.

# Microsoft Fabric Data Factory Performance remediate Systematic approach to diagnosing and resolving performance issues in Microsoft Fabric Data Factory pipelines, copy activities, and dataflows. ## When to Use This Skill - Pipeline execution takes longer than expected - Copy activities are slow or appear stuck - Activities show "Not Started" status for extended periods - Capacity throttling errors (HTTP 430, TooManyRequestsForCapacity) - Throughput is lower than expected for copy operations - Dataflow Gen2 refresh is slow or timing out - Pipeline monitoring shows performance degradation over time - Need to optimize parallelism, DIU, or partitioning settings ## Prerequisites - Access to Microsoft Fabric workspace with Contributor or higher role - Familiarity with the Fabric Monitoring Hub - Understanding of Fabric capacity SKUs and their limits - PowerShell 7+ for running diagnostic scripts ## Diagnostic Workflow ### Step 1: Identify the Bottleneck Category Determine which category your issue falls into: | Category | Symptoms | Start Here | | ------------------- | ------------------------------------------- | ----------------------------------------------------------------------------------------- | | Copy Activity Slow | Low throughput, long transfer duration | [copy-activity-tuning.md](./references/copy-activity-tuning.md)
