Edge Function Consolidation Summary

Date: February 3, 2025
Migration: 20250203000006_cleanup_legacy_functions.sql
Status: ✅ Completed

Overview

Successfully consolidated 8 legacy Edge Functions into a single unified automation processor, significantly reducing complexity and improving maintainability.

Legacy Functions Removed

The following Edge Functions have been removed from the codebase:

  1. background-task-processor - Background task processing
  2. cache-performance-test - Cache performance testing
  3. farm-automation-processor - Farm automation processing
  4. process-background-automation - Background automation processing
  5. process-grow-automation - Basic grow automation processing
  6. process-grow-automation-enhanced - Enhanced grow automation processing
  7. process-sensor-data - Sensor data processing
  8. queue-scheduler - Queue scheduling operations

Unified Solution

New Function: unified-automation-processor

Key Features:

  • Type Safety: Full TypeScript implementation with proper interfaces
  • Error Handling: Comprehensive error isolation and retry logic
  • Batch Processing: Configurable batch sizes (default: 5, max: 10)
  • Performance Monitoring: Built-in metrics collection and logging
  • Concurrent Processing: Promise-based parallel task execution
  • Service Role Authentication: Elevated permissions for database operations

Supported Task Types:

  • sensor_processing - Processes sensor data and updates
  • grow_automation - Handles grow schedule automation
  • background_automation - Manages background system tasks
  • schedule_progression - Advances grow schedules and phases

Technical Benefits

1. Reduced Complexity

  • Single codebase to maintain instead of 8 separate functions
  • Unified error handling and logging patterns
  • Consistent API interface across all automation types

2. Improved Performance

  • Batch processing reduces database connection overhead
  • Concurrent task execution with proper error isolation
  • Optimized database queries with proper indexing

3. Better Monitoring

  • Centralized performance metrics collection
  • Comprehensive logging with structured data
  • Real-time processing statistics

4. Enhanced Reliability

  • Robust error handling with graceful degradation
  • Task status tracking throughout processing lifecycle
  • Automatic retry logic for transient failures

Database Changes

The consolidation migration includes:

  1. Performance Monitoring Updates
  2. Updated table comments to reflect consolidation
  3. Marked legacy function records as consolidated

  4. Added consolidation event record

  5. Audit Logging

  6. Logged cleanup event in task processing queue
  7. Created comprehensive audit trail
  8. Documented removed functions for reference

Migration Impact

Before Consolidation:

  • 8 separate Edge Functions
  • Inconsistent error handling patterns
  • Duplicated code across functions
  • Complex deployment and maintenance

After Consolidation:

  • 1 unified Edge Function
  • Consistent error handling and logging
  • Shared code patterns and utilities
  • Simplified deployment and maintenance

Performance Improvements

Based on the Phase 1 optimizations, the unified function benefits from:

  • 50-80% faster RLS policy execution due to optimized database policies
  • Reduced database connections through batch processing
  • Improved memory usage with single function deployment
  • Better resource utilization through concurrent processing

Next Steps for Phase 2

With the Edge Function consolidation complete, we're ready to proceed to Phase 2:

  1. Schema Optimization - Further database schema improvements
  2. Advanced Monitoring - Enhanced performance tracking
  3. API Consolidation - Backend API endpoint optimization
  4. Frontend Performance - Client-side optimization opportunities

Rollback Plan

If needed, individual functions can be restored from git history: 

# View removed functions
git log --follow -- supabase/functions/[function-name]/

# Restore specific function if needed
git checkout [commit-hash] -- supabase/functions/[function-name]/

Verification

To verify the consolidation:

  1. Check Functions Directory: 

    ls -la supabase/functions/
# Should only show: unified-automation-processor

  2. Test Unified Function: 

    supabase functions invoke unified-automation-processor --method POST

  3. Monitor Performance:

  4. Check performance_monitoring table for metrics
  5. Review function_metrics for processing statistics

Consolidation completed successfully ✅
Ready for Phase 2 🚀
