# Automation Refactor - Complete Example
|
|
|
|
This document demonstrates a comprehensive workflow refactoring scenario using the automation-refactor skill.
|
|
|
|
## Scenario
|
|
|
|
**User Request**: "Optimize this Power Automate flow to reduce API calls and improve error handling"
|
|
|
|
**Platform**: Power Automate
|
|
|
|
**Original Flow Purpose**: Process new SharePoint list items by fetching user details and sending notification emails
|
|
|
|

|
|
|
|
## Phase 1: Original Flow (Before Refactoring)
|
|
|
|
### Original flow.json
|
|
|
|
```json
|
|

"definition": {
|
|
"$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",

},
|
|
"recurrence": {
|
|
"frequency": "Minute",
|
|
"interval": 5
|
|
}
|
|
}
|
|
},
|
|
"actions": {
|
|
"Get_items": {
|
|
"type": "ApiConnection",
|
|
"inputs": {

|
|
"table": "RequestsList"
|
|
}
|
|
},
|
|
"runAfter": {}
|
|
},
|
|
"Apply_to_each": {
|
|
"type": "Foreach",
|
|
"foreach": "@body('Get_items')?['value']",
|
|
"actions": {
|
|
"Get_user": {
|
|
"type": "ApiConnection",
|
|
"inputs": {

|
|
},
|
|
"parameters": {
|
|
"id": "@items('Apply_to_each')?['CreatedBy']?['Email']"
|
|
}
|
|
}
|
|
},
|
|
"Send_email": {
|
|
"type": "ApiConnection",
|
|
"inputs": {
|
|
"host": {
|
|
"connectionName": "shared_office365",
|
|
"operationId": "SendEmailV2",
|

}
|
|
},
|
|
"runAfter": {
|
|
"Get_user": ["Succeeded"]
|
|
}
|
|
}
|
|
},
|
|
"runAfter": {
|
|
"Get_items": ["Succeeded"]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
### Problems Identified
|
|
|
|
1. **Performance Issues**:
|
|
- Gets ALL items instead of just new ones
|
|
- Makes individual API call for each user (N+1 query problem)
|
|
- Sequential processing (no concurrency)
|
|
- Total: 1 + N + N = 2N+1 API calls for N items
|
|
|
|
2. **Reliability Issues**:
|
|
- No error handling
|
|
- No retry logic
|
|
- Single failure breaks entire flow
|
|
- No logging
|
|
|
|
3. **Maintainability Issues**:
|
|
- Generic action names ("Get_items", "Apply_to_each")
|
|
- No comments or documentation
|
|
- Hardcoded values
|
|
- No variable initialization
|
|
|
|
4. **Security Issues**:
|
|
- Site URL hardcoded in JSON
|
|
- No input validation
|
|
|

|
|
## Phase 2: Analysis & Research
|
|
|
|
### Documentation Research Findings
|
|
|
|
From `Docs/PowerAutomateDocs/SharePoint/overview.md`:
|
|
- API Limit: 600 calls per 60 seconds
|
|
- Recommendation: Use $expand to fetch related data
|
|
- Best practice: Filter items at source with $filter
|
|
|
|
From `Docs/PowerAutomateDocs/Excel/overview.md`:
|
|
- Recommendation: Use $select to limit fields
|
|
- Pagination: Default 256 rows, can increase to 5000
|
|
|
|
From `Docs/PowerAutomateDocs/BuiltIn/control.md`:
|
|
- Error handling: Use Scope with Configure run after
|
|
- Concurrency: Can be enabled for independent operations
|
|
|
|
### Optimization Strategy
|
|
|
|
1. **Reduce API Calls**:
|
|
- Use $expand to get user data with items (1 call instead of N+1)
|
|
- Add $filter to get only recent items
|
|
- Add $select to fetch only needed fields
|
|
|
|
2. **Add Error Handling**:
|
|
- Wrap operations in Scopes
|
|
- Add Configure run after for error catching
|
|
- Log errors for debugging
|
|
|
|
3. **Improve Maintainability**:
|
|
- Rename actions descriptively
|
|
- Initialize variables at start
|
|
- Add comments via Compose actions
|
|
|
|
4. **Enhance Reliability**:
|
|
- Add retry logic for transient failures
|
|
- Validate data before processing
|
|
- Add monitoring points
|
|

## Phase 4: Refactoring Report
|
|
|
|
### Summary
|
|
|
|
- **Platform**: Power Automate
|
|
- **Flow Name**: Request Notification System
|
|
- **Refactoring Goals**: Reduce API calls, improve error handling, enhance maintainability
|
|
- **Changes Applied**: 12 major improvements
|
|
- **Functional Impact**: Maintained equivalence - same notifications sent, same logic
|
|
- **Performance Improvement**: ~95% reduction in API calls (2N+1 → 1-2 calls)
|
|
|
|
---
|
|
|
|
### Changes Implemented
|
|
|
|
#### Performance Optimizations
|
|
|
|
1. **Eliminated N+1 Query Problem**
|
|
- **Before**: 1 call to get items + N calls to get users = N+1 calls
|
|
- **After**: 1 call with $expand to get items with user data = 1 call
|
|
- **Impact**: For 100 items: 101 calls → 1 call (99% reduction)
|
|
- **Documentation**: Docs/PowerAutomateDocs/SharePoint/overview.md - "Use $expand for related data"
|
|
|
|
2. **Added Data Filtering at Source**
|
|
- **Before**: Fetched all items (potentially thousands)
|
|
- **After**: $filter for items in last 24 hours only
|
|
- **Impact**: Reduces data transfer and processing time
|
|
- **Documentation**: Docs/PowerAutomateDocs/SharePoint/actions.md - "Filter at source with $filter"
|
|
|
|
3. **Optimized Field Selection**
|
|
- **Before**: Retrieved all fields
|
|
- **After**: $select for only needed fields (ID, Title, Author, Created)
|
|
- **Impact**: 50-70% reduction in response size
|
|
- **Documentation**: Docs/PowerAutomateDocs/SharePoint/overview.md - "Use $select to minimize data"
|
|
|
|
4. **Enabled Concurrency**
|
|
- **Before**: Sequential processing (1 email at a time)
|
|
- **After**: Process 5 items concurrently
|
|
- **Impact**: 5x faster email sending (safe for independent operations)
|
|
- **Documentation**: Docs/PowerAutomateDocs/BuiltIn/control.md - "Concurrency for independent actions"
|
|
|
|
#### Reliability Improvements
|
|
|
|
5. **Added Comprehensive Error Handling**
|
|
- Wrapped main logic in Scope with error catching
|
|
- Error Handling Scope runs on failure/timeout
|
|
- Logs all errors for debugging
|
|
- **Documentation**: Docs/PowerAutomateDocs/BuiltIn/control.md - "Scope-based error handling"
|
|
|
|
6. **Implemented Retry Logic**
|
|
- Send email action has exponential backoff retry (3 attempts)
|
|
- Handles transient Office 365 failures gracefully
|
|
- **Documentation**: Docs/PowerAutomateDocs/Outlook/overview.md - "Retry policy for transient failures"
|
|
|
|
7. **Added Input Validation**
|
|
- Checks if items array is not empty before processing
|
|
- Validates email address exists before sending
|
|
- Prevents null reference errors
|
|
- **Documentation**: Docs/PowerAutomateDocs/BuiltIn/control.md - "Validate inputs"
|
|
|
|
8. **Implemented Error Logging**
|
|
- ErrorLog variable tracks all issues
|
|
- Captures missing emails, failed sends
|
|
- Included in admin notification for review
|
|
- **Custom best practice**
|
|
|
|
#### Maintainability Enhancements
|
|
|
|
9. **Renamed All Actions Descriptively**
|
|
- "Get_items" → "Get_Recent_Items_With_User_Details"
|
|
- "Apply_to_each" → "Process_Each_Request"
|
|
- "Send_email" → "Send_Notification_Email"
|
|
- Makes flow immediately understandable
|
|
- **Documentation**: Docs/PowerAutomateDocs/ - "Use clear, descriptive names"
|
|
|
|
10. **Added Descriptive Comments**
|
|
- Description field on 8 key actions
|
|
- Explains WHY each action exists
|
|
- Helps future maintainers understand logic
|
|
- **Best practice**
|
|
|
|
11. **Parameterized Configuration**
|
|
- SharePointSiteURL as parameter (not hardcoded)
|
|
- ListName as parameter
|
|
- Easy to duplicate for other sites/lists
|
|
- **Documentation**: Docs/PowerAutomateDocs/ - "Use parameters for reusability"
|
|
|
|
12. **Organized into Logical Scopes**
|
|
- Main_Processing_Scope: Core logic
|
|
- Error_Handling_Scope: Error recovery
|
|
- Clear separation of concerns
|
|
- **Documentation**: Docs/PowerAutomateDocs/BuiltIn/control.md - "Organize with Scopes"
|

### Testing Recommendations
|
|
|
|
#### Functional Testing
|
|
|
|
1. **Verify Same Emails Sent**
|
|
- Create test item in SharePoint
|
|
- Confirm email received by author
|
|
- Verify email content matches original
|
|
|
|
2. **Test with Multiple Items**
|
|
- Create 10 test items with different authors
|
|
- Verify all 10 emails sent
|
|
- Confirm no duplicates or missing emails
|
|
|
|
3. **Test Error Scenarios**
|
|
- Create item with user that has no email
|
|
- Verify error logged in ErrorLog variable
|
|
- Confirm flow doesn't fail completely
|
|
|
|
4. **Test Empty Scenario**
|
|
- Run flow with no recent items
|
|
- Verify flow completes successfully
|
|
- Check no errors logged
|
|
|
|
#### Performance Testing
|
|
|
|
1. **Measure API Call Reduction**
|
|
- **Before**: Check flow run history - count API calls
|
|
- **After**: Check flow run history - count API calls
|
|
- **Expected**: ~95% reduction (101 → 1-5 calls for 100 items)
|
|
|
|
2. **Measure Execution Time**
|
|
- **Before**: Note total run duration for 100 items
|
|
- **After**: Note total run duration for 100 items
|
|
- **Expected**: 80-90% faster due to concurrency
|
|
|
|
3. **Load Testing**
|
|
- Create 100 test items
|
|
- Verify all processed successfully
|
|
- Check for throttling errors (should be none)
|
|
|
|
#### Error Testing
|
|
|
|
1. **Test Office 365 Outage**
|
|
- Temporarily disable Office 365 connection
|
|
- Verify Error_Handling_Scope runs
|
|
- Verify admin notification sent
|
|
- Verify ErrorLog captured issue
|
|
|
|
2. **Test SharePoint Throttling**
|
|
- Intentionally trigger throttling (make many rapid calls)
|
|
- Verify retry logic activates
|
|
- Verify eventual success or logged failure
|
|
|
|
3. **Test Invalid Data**
|
|
- Create item with null/invalid author
|
|
- Verify validation catches it
|
|
- Verify logged in ErrorLog
|
