# JSONB Elimination Plan
|
||||
|
||||
**PROJECT RULE**: NEVER STORE JSON OR JSONB IN SQL COLUMNS
|
||||
*"If your data is relational, model it relationally. JSON blobs destroy queryability, performance, data integrity, and your coworkers' sanity. Just make the damn tables. NO JSON OR JSONB INSIDE DATABASE CELLS!!!"*
|
||||
|
||||
---
|
||||
|
||||
## 📊 Current JSONB Violations
|
||||
|
||||
### Critical Violations (Must Fix)
|
||||
- ❌ `rides.coaster_stats` - JSONB column storing coaster-specific statistics
|
||||
- ❌ `rides.technical_specs` - JSONB column storing technical specifications
|
||||
- ❌ `ride_models.technical_specs` - JSONB column storing model specifications
|
||||
- ❌ `user_top_lists.items` - JSONB array storing list items
|
||||
|
||||
### Migration Status
|
||||
- ⏳ **Phase 1**: Creating relational tables (IN PROGRESS)
|
||||
- ✅ `coaster_stats` table created
|
||||
- ✅ `technical_specifications` table created
|
||||
- ⏳ `list_items` table (pending schema verification)
|
||||
- ⏳ **Phase 2**: Data migration scripts (PENDING)
|
||||
- ⏳ **Phase 3**: Drop JSONB columns (PENDING)
|
||||
- ⏳ **Phase 4**: Update application code (PENDING)
|
||||
|
||||
---
|
||||
|
||||
## ✅ Acceptable JSONB Usage
|
||||
|
||||
These are the ONLY approved JSONB columns (configuration objects, no relational structure):
|
||||
|
||||
### User Preferences (Configuration)
|
||||
- ✅ `user_preferences.unit_preferences` - User measurement preferences
|
||||
- ✅ `user_preferences.privacy_settings` - Privacy configuration
|
||||
- ✅ `user_preferences.notification_preferences` - Notification settings
|
||||
|
||||
### System Configuration
|
||||
- ✅ `admin_settings.setting_value` - System configuration values
|
||||
- ✅ `notification_channels.configuration` - Channel config objects
|
||||
- ✅ `admin_audit_log.details` - Audit metadata (non-queryable)
|
||||
|
||||
### Legacy Support (To Be Eliminated)
|
||||
- ⚠️ `content_submissions.content` - Has strict validation, but should migrate to `submission_metadata` table
|
||||
- ⚠️ `rides.former_names` - Array field, should migrate to `entity_former_names` table
|
||||
|

|
||||
|
||||
## 🎯 Refactoring Plan
|
||||
|
||||
### 1. Coaster Stats → Relational Table (2 hours)
|
||||
|
||||
**Current**: `rides.coaster_stats JSONB`
|
||||
|
||||
**New Structure**:
|
||||
```sql
|
||||
CREATE TABLE public.coaster_stats (
|
||||
id UUID PRIMARY KEY,
|
||||
ride_id UUID REFERENCES rides(id),
|
||||
stat_type TEXT CHECK (stat_type IN (
|
||||
'vertical_angle', 'airtime_seconds', 'track_material',
|
||||
'train_type', 'seats_per_train', 'number_of_trains'
|
||||
)),
|
||||
stat_value TEXT NOT NULL,
|
||||
stat_unit TEXT,
|
||||
display_order INTEGER,
|
||||
UNIQUE(ride_id, stat_type)
|
||||
);
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ Queryable: `SELECT * FROM coaster_stats WHERE stat_type = 'vertical_angle' AND stat_value > 90`
|
||||
- ✅ Indexed: Fast lookups by ride_id or stat_type
|
||||
- ✅ Type safe: No JSON parsing errors
|
||||
- ✅ Referential integrity: Cascade deletes when ride is deleted
|
||||
|
||||
---
|
||||
|
||||
### 2. Technical Specs → Relational Table (2 hours)
|
||||
|
||||
**Current**:
|
||||
- `rides.technical_specs JSONB`
|
||||
- `ride_models.technical_specs JSONB`
|
||||
|
||||
**New Structure**:
|
||||
```sql
|
||||
CREATE TABLE public.technical_specifications (
|
||||
id UUID PRIMARY KEY,
|
||||
entity_type TEXT CHECK (entity_type IN ('ride', 'ride_model')),
|
||||
entity_id UUID NOT NULL,
|
||||
spec_name TEXT NOT NULL,
|
||||
spec_value TEXT NOT NULL,
|
||||
spec_unit TEXT,
|
||||
display_order INTEGER,
|
||||
UNIQUE(entity_type, entity_id, spec_name)
|
||||
);
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ Unified specs table for both rides and models
|
||||
- ✅ Easy filtering: `WHERE spec_name = 'track_gauge'`
|
||||
- ✅ Easy sorting by display_order
|
||||
- ✅ No JSON parsing in queries
|
||||
|
||||
---
|
||||
|
||||
### 3. User Top Lists → Relational Table (1.5 hours)
|
||||
|
||||
**Current**: `user_top_lists.items JSONB` (array of `{id, position, notes}`)
|
||||
|
||||
**New Structure**:
|
||||
```sql
|
||||
CREATE TABLE public.list_items (
|
||||
id UUID PRIMARY KEY,
|
||||
list_id UUID REFERENCES user_top_lists(id),
|
||||
entity_type TEXT CHECK (entity_type IN ('park', 'ride', 'coaster')),
|
||||
entity_id UUID NOT NULL,
|
||||
position INTEGER NOT NULL,
|
||||
notes TEXT,
|
||||
UNIQUE(list_id, position),
|
||||
UNIQUE(list_id, entity_id)
|
||||
);
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ Proper foreign key constraints to entities
|
||||
- ✅ Easy reordering with position updates
|
||||
- ✅ Can join to get entity details directly
|
||||
- ✅ No array manipulation in application code
|
||||
|
||||
---
|
||||
|
||||
### 4. Former Names → Relational Table (1 hour)
|
||||
|
||||
**Current**: `rides.former_names TEXT[]`
|
||||
|
||||
**New Structure**:
|
||||
```sql
|
||||
CREATE TABLE public.entity_former_names (
|
||||
id UUID PRIMARY KEY,
|
||||
entity_type TEXT CHECK (entity_type IN ('park', 'ride', 'company')),
|
||||
entity_id UUID NOT NULL,
|
||||
former_name TEXT NOT NULL,
|
||||
used_from DATE,
|
||||
used_until DATE,
|
||||
change_reason TEXT,
|
||||
display_order INTEGER,
|
||||
created_at TIMESTAMPTZ DEFAULT NOW()
|
||||
);
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ Track date ranges for name changes
|
||||
- ✅ Add reasons for name changes
|
||||
- ✅ Query by date range
|
||||
- ✅ Unified table for all entities
|
||||
|
||||

|
||||
|
||||
## 📈 Performance Benefits
|
||||
|
||||
### Before (JSONB)
|
||||
```sql
|
||||
-- Slow, requires full table scan + JSON parsing
|
||||
SELECT * FROM rides
|
||||
WHERE coaster_stats->>'vertical_angle' > '90';
|
||||
|
||||
-- Cannot index JSON keys efficiently
|
||||
-- Cannot enforce referential integrity
|
||||
-- Type errors only caught at runtime
|
||||
```
|
||||
|
||||
### After (Relational)
|
||||
```sql
|
||||
-- Fast, uses indexes
|
||||
SELECT r.* FROM rides r
|
||||
JOIN coaster_stats cs ON cs.ride_id = r.id
|
||||
WHERE cs.stat_type = 'vertical_angle'
|
||||
AND cs.stat_value::numeric > 90;
|
||||
|
||||
-- Proper indexes on ride_id and stat_type
|
||||
-- Database enforces constraints
|
||||
-- Type errors caught at migration time
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚀 Implementation Priority
|
||||
|
||||
1. **HIGH**: `coaster_stats` - Most frequently queried
|
||||
2. **HIGH**: `technical_specs` - Used across rides and models
|
||||
3. **MEDIUM**: `list_items` - User-facing feature
|
||||
4. **MEDIUM**: `former_names` - Historical data tracking
|
||||
5. **LOW**: `content_submissions.content` - Has validation, migrate when capacity allows
|
||||
|
||||

|
||||
|
||||
## ✅ Completed Migrations
|
||||
|
||||
- ✅ `reviews.photos` → `review_photos` table (migration 20251001231631)
|
||||
|
||||
---
|
||||
|
||||
## 📝 Migration Checklist (Per Table)
|
||||
|
||||
For each JSONB elimination:
|
||||
|
||||
- [ ] Create new relational table with proper schema
|
||||
- [ ] Add RLS policies matching parent table
|
||||
- [ ] Create indexes for performance
|
||||
- [ ] Write data migration script to copy existing data
|
||||
- [ ] Update all application queries to use new table
|
||||
- [ ] Update all forms/components to use new structure
|
||||
- [ ] Test thoroughly in staging
|
||||
- [ ] Deploy migration to production
|
||||
- [ ] Drop JSONB column after verification
|
||||
- [ ] Update documentation
|
||||
|
||||

|
||||
|
||||
