🚨 CRITICAL GUIDELINES

Windows File Path Requirements

MANDATORY: Always Use Backslashes on Windows for File Paths

When using Edit or Write tools on Windows, you MUST use backslashes (\) in file paths, NOT forward slashes (/).

Examples:

• ❌ WRONG: D:/repos/project/file.tsx
• ✅ CORRECT: D:\repos\project\file.tsx

This applies to:

• Edit tool file_path parameter
• Write tool file_path parameter
• All file operations on Windows systems

Documentation Guidelines

NEVER create new documentation files unless explicitly requested by the user.

• Priority: Update existing README.md files rather than creating new documentation
• Repository cleanliness: Keep repository root clean - only README.md unless user requests otherwise
• Style: Documentation should be concise, direct, and professional - avoid AI-generated tone
• User preference: Only create additional .md files when user specifically asks for documentation

This skill provides comprehensive reference information about Azure Data Factory, including official documentation sources, CI/CD deployment methods, and troubleshooting resources. Use this to access detailed ADF knowledge on-demand.

🚨 CRITICAL 2025 UPDATE: Deprecated Features

Apache Airflow Workflow Orchestration Manager - DEPRECATED

Status: Available only for existing customers as of early 2025 Retirement Date: Not yet announced, but feature is officially deprecated Impact: New customers cannot provision Apache Airflow in Azure Data Factory

Official Deprecation Notice:

• Apache Airflow Workflow Orchestration Manager is deprecated with no retirement date set
• Only existing deployments can continue using this feature
• No new Airflow integrations can be created in ADF

Migration Path:

• Recommended: Migrate to Fabric Data Factory with native Airflow support
• Alternative: Use standalone Apache Airflow deployments (Azure Container Instances, AKS, or VM-based)
• Alternative: Migrate orchestration logic to native ADF pipelines with control flow activities

Why Deprecated:

• Microsoft focus shifted to Fabric Data Factory as the unified data integration platform
• Fabric provides modern orchestration capabilities superseding Airflow integration
• Limited adoption and maintenance burden for standalone Airflow feature in ADF

Action Required:

• If using Airflow in ADF: Plan migration within 12-18 months
• For new projects: Do NOT use Airflow in ADF - use Fabric or native ADF patterns
• Monitor Microsoft announcements for official retirement timeline

CI/CD Deployment Methods

Modern Automated Approach (Recommended)

npm Package: @microsoft/azure-data-factory-utilities

• Latest Version: 1.0.3+ (check npm for current version)
• npm URL: https://www.npmjs.com/package/@microsoft/azure-data-factory-utilities
• Node.js Requirement: Version 20.x or compatible

Key Features:

• Validates ADF resources independently of service
• Generates ARM templates programmatically
• Enables true CI/CD without manual publish button
• Supports preview mode for selective trigger management

package.json Configuration:

{
  "scripts": {
    "build": "node node_modules/@microsoft/azure-data-factory-utilities/lib/index",
    "build-preview": "node node_modules/@microsoft/azure-data-factory-utilities/lib/index --preview"
  },
  "dependencies": {
    "@microsoft/azure-data-factory-utilities": "^1.0.3"
  }
}

Commands:

# Validate resources
npm run build validate <rootFolder> <factoryId>

# Generate ARM templates
npm run build export <rootFolder> <factoryId> [outputFolder]

# Preview mode (only stop/start modified triggers)
npm run build-preview export <rootFolder> <factoryId> [outputFolder]

Official Documentation:

• URL: https://learn.microsoft.com/en-us/azure/data-factory/continuous-integration-delivery-improvements
• Last Updated: January 2025
• Topics: Setup, configuration, build commands, CI/CD integration

Traditional Manual Approach (Legacy)

Method: Git integration + Publish button

Process:

1. Configure Git integration in ADF UI (Dev environment only)
2. Make changes in ADF Studio
3. Click "Publish" button to generate ARM templates
4. Templates saved to adf_publish branch
5. Release pipelines deploy from adf_publish branch

When to Use:

• Migrating from existing setup
• No build pipeline infrastructure
• Simple deployments without validation

Limitations:

• Requires manual publish action
• No validation until publish
• Not true CI/CD (manual step required)
• Can't validate on pull requests

Migration Path: Modern approach recommended for new implementations

Troubleshooting Resources

Official Troubleshooting Guide

URL: https://learn.microsoft.com/en-us/azure/data-factory/ci-cd-github-troubleshoot-guide Last Updated: January 2025

Common Issues Covered:

1. Template parameter validation errors
2. Integration Runtime type cannot be changed
3. ARM template size exceeds 4MB limit
4. Git connection problems
5. Authentication failures
6. Deployment errors

Diagnostic Logs

Enable Diagnostic Settings:

Azure Portal → Data Factory → Diagnostic settings → Add diagnostic setting
Send to: Log Analytics workspace

Logs to Enable:
- PipelineRuns
- TriggerRuns
- ActivityRuns
- SandboxPipelineRuns
- SandboxActivityRuns

Kusto Queries for Troubleshooting:

// Failed pipeline runs in last 24 hours
ADFPipelineRun
| where Status == "Failed"
| where TimeGenerated > ago(24h)
| project TimeGenerated, PipelineName, RunId, Status, ErrorMessage, Parameters
| order by TimeGenerated desc

// Failed CI/CD deployments
ADFActivityRun
| where ActivityType == "ExecutePipeline"
| where Status == "Failed"
| where TimeGenerated > ago(7d)
| project TimeGenerated, PipelineName, ActivityName, ErrorCode, ErrorMessage
| order by TimeGenerated desc

// Performance analysis
ADFActivityRun
| where TimeGenerated > ago(7d)
| extend DurationMinutes = datetime_diff('minute', End, Start)
| summarize AvgDuration = avg(DurationMinutes) by ActivityType, ActivityName
| where AvgDuration > 10
| order by AvgDuration desc

Common Error Patterns

Error: "Template parameters are not valid"

• Cause: Deleted triggers still referenced in parameters
• Solution: Regenerate ARM template or use PrePostDeploymentScript cleanup

Error: "Updating property type is not supported"

• Cause: Trying to change Integration Runtime type
• Solution: Delete and recreate IR (not in-place update)

Error: "Operation timed out"

• Cause: Network connectivity, large data volume, insufficient compute
• Solution: Increase timeout, optimize query, increase DIUs

Error: "Authentication failed"

• Cause: Service principal expired, missing permissions, wrong credentials
• Solution: Verify credentials, check role assignments, renew if expired

Best Practices

Git Configuration

Only Configure Git on Development ADF:

• Development: Git-integrated for source control
• Test: CI/CD deployment only (no Git)
• Production: CI/CD deployment only (no Git)

Rationale: Prevents accidental manual changes in higher environments

Multi-Environment Strategy

Environment Flow:
Dev (Git) → Build → Test → Approval → Production
            ↓
        ARM Templates

Parameter Management:

• Separate parameter file per environment
• Store secrets in Azure Key Vault
• Reference Key Vault in parameter files
• Never commit secrets to source control

Monitoring and Alerting

Set up alerts for:

• Build pipeline failures
• Deployment failures
• Pipeline run failures
• Performance degradation
• Cost anomalies

Recommended Tools:

• Azure Monitor (Metrics and Alerts)
• Log Analytics (Kusto queries)
• Application Insights (for custom logging)
• Azure Advisor (optimization recommendations)
