Migration Consolidation Summary

Overview

Successfully consolidated 23+ individual migration files into a single master database schema migration. This provides a clean, maintainable foundation for the vertical farming management system.

What Was Done

1. Master Migration Created

  • File: 20250101000000_master_database_schema.sql
  • Size: ~30KB comprehensive schema
  • Timestamp: Early date (2025-01-01) ensures it runs first in deployments

2. Migration Files Cleaned Up

  • Removed: 23+ old migration files
  • Backed up: All old migrations stored in supabase/migrations_backup/
  • Kept: Only the master migration file

3. PGMQ Queue System Fixed

  • Issue: Old migrations used incorrect function pgmq.create_queue()
  • Fix: Updated to correct function pgmq.create()
  • Verified: All 6 queues working correctly

Master Migration Contents

Core Database Schema

  • Users: profiles table with role-based access
  • Farms: Hierarchical structure (farms → rows → racks → shelves)
  • Devices: Device types, devices, and sensor readings
  • Integrations: Home Assistant, MQTT, webhook, and API integrations

Queue System (PGMQ)

  • 6 Queues: farm_automation, sensor_processing, notifications, analytics, maintenance, background_tasks
  • Supporting Tables: queue_config, task_logs, background_tasks
  • Functions: send_queue_message() with automatic logging

Security & Performance

  • RLS Policies: Row-level security for all tables
  • Indexes: Performance optimized for common queries
  • Triggers: Automatic updated_at timestamp management

Storage & Realtime

  • Storage Buckets: avatars, farm-images, device-images
  • Realtime: Enabled for key tables (devices, sensor readings, etc.)

Initial Data

  • Device Types: Temperature sensors, humidity sensors, pH sensors, LED lights, pumps, fans, controllers
  • Queue Configuration: Retry policies and settings for each queue
  • Background Tasks: Scheduled maintenance and cleanup jobs

Queue System Status

Active Queues

✅ farm_automation      - Device control and automation tasks
✅ sensor_processing    - Sensor data processing and analysis  
✅ notifications        - Alerts and user notifications
✅ analytics           - Data aggregation and reporting
✅ maintenance         - System maintenance and health checks
✅ background_tasks    - Scheduled background operations

Queue Functions Working

  • pgmq.create() - Create new queues
  • pgmq.send() - Send messages to queues
  • pgmq.read() - Read messages from queues
  • public.send_queue_message() - Send with automatic logging

Benefits of Consolidation

Maintenance

  • ✅ Single source of truth for database schema
  • ✅ Easier to understand and modify
  • ✅ No dependency conflicts between migrations
  • ✅ Clean migration history

Deployment

  • ✅ Faster deployment (1 migration vs 23+)
  • ✅ Reduced risk of migration failures
  • ✅ Easier rollback if needed
  • ✅ Consistent across environments

Development

  • ✅ New developers can understand schema quickly
  • ✅ Clear documentation of all database objects
  • ✅ Defensive SQL prevents conflicts
  • ✅ Well-organized and commented code

Verification Status

Database Objects

  • ✅ All tables created successfully
  • ✅ All indexes and constraints applied
  • ✅ All triggers and functions working
  • ✅ RLS policies active and tested

PGMQ Integration

  • ✅ All 6 queues operational
  • ✅ Message sending/receiving working
  • ✅ Task logging functional
  • ✅ Queue configuration applied

Storage & Security

  • ✅ Storage buckets created
  • ✅ RLS policies protecting data
  • ✅ Realtime subscriptions active
  • ✅ Initial data populated

Next Steps

  1. Test Full Application: Verify all application features work with consolidated schema
  2. Update Documentation: Update any docs that reference old migration files
  3. Deploy to Staging: Test the master migration in staging environment
  4. Production Deployment: Apply to production when ready

Files Changed

Created

  • supabase/migrations/20250101000000_master_database_schema.sql
  • tests/queues/test_queue_system.sql (updated)
  • MIGRATION_CONSOLIDATION_SUMMARY.md

Moved

  • All old migration files → supabase/migrations_backup/

Functions Available

  • public.uuid_generate_v4() - UUID generation
