Database Design: How MyPosts Structures Data for Speed

Database Philosophy

MyPosts leverages Supabase's PostgreSQL database for robust data management with real-time capabilities. The schema balances normalization with query performance.

Core Tables

Users Table

Stores account information:

- id (UUID, primary)
- email (unique)
- created_at
- subscription_tier
- settings (JSONB)

Accounts Table

Twitter account connections:

- id (UUID, primary)
- user_id (foreign key)
- twitter_username
- encrypted_tokens (AES-256)
- status (active/paused)

Posts Table

Content and scheduling:

- id (UUID, primary)
- account_id (foreign key)
- content (text)
- scheduled_at (timestamp)
- published_at (timestamp)
- status (draft/scheduled/published/failed)
- metadata (JSONB)

Real-Time Features

Live Updates

Supabase enables:

• Instant post status updates
• Real-time analytics
• Live collaboration
• Activity feeds

Subscription System

const subscription = supabase
  .from('posts')
  .on('INSERT', handleNewPost)
  .on('UPDATE', handleUpdate)
  .subscribe()

Performance Optimizations

Indexing Strategy

Key indexes for speed:

• scheduled_at (B-tree)
• account_id + status (composite)
• published_at (partial)
• user_id (foreign key)

Query Optimization

• Prepared statements
• Connection pooling
• Query caching
• Batch operations

Security Measures

Row Level Security

PostgreSQL RLS policies:

CREATE POLICY "Users can only see own posts"
ON posts FOR SELECT
USING (auth.uid() = user_id);

Encryption

Sensitive data protection:

• API tokens: AES-256
• Passwords: bcrypt
• SSL connections
• Encrypted backups

Scaling Architecture

Partitioning

Large table management:

• Posts partitioned by month
• Archives for old data
• Automatic maintenance
• Query routing

Read Replicas

Load distribution:

• Write to primary
• Read from replicas
• Automatic failover
• Geographic distribution

Analytics Tables

Usage Tracking

usage_stats:
- user_id
- date
- posts_created
- tokens_used
- api_calls

Performance Metrics

post_analytics:
- post_id
- impressions
- engagements
- clicks
- timestamp

Backup Strategy

Automated Backups

• Daily snapshots
• Point-in-time recovery
• Cross-region replication
• 30-day retention

Migration System

Version Control

Database evolution:

• Sequential migrations
• Rollback capability
• Testing environment
• Zero-downtime updates

Edge Functions

Serverless Logic

Supabase Edge Functions handle:

• Webhook processing
• Data validation
• Complex calculations
• Third-party integrations

The database architecture ensures MyPosts scales from single users to enterprise teams!
