Data Models & Schemas
Database Schema
-- Users Table CREATE TABLE users ( id UUID PRIMARY KEY, email VARCHAR(255) UNIQUE, username VARCHAR(100), avatar_url TEXT, created_at TIMESTAMP, updated_at TIMESTAMP ); -- Sessions Table CREATE TABLE sessions ( id UUID PRIMARY KEY, name VARCHAR(255), language VARCHAR(50), created_by UUID REFERENCES users(id), created_at TIMESTAMP, updated_at TIMESTAMP ); -- Executions Table CREATE TABLE executions ( id UUID PRIMARY KEY, session_id UUID REFERENCES sessions(id), code TEXT, output TEXT, status VARCHAR(50), executed_at TIMESTAMP );
API Models
// TypeScript Interfaces
interface User {
id: string
email: string
username: string
avatarUrl?: string
isOnline: boolean
cursor?: CursorPosition
}
interface Session {
id: string
name: string
language: string
createdBy: string
participants: User[]
document: Y.Doc
}
interface ExecutionJob {
id: string
sessionId: string
code: string
language: string
status: 'pending' | 'running' | 'completed' | 'failed'
output?: string
error?: string
}Security & Performance Considerations
Security Measures
- Sandboxed Execution: All code runs in isolated Docker containers with resource limits
- Authentication: JWT-based authentication with session management
- Input Validation: Comprehensive validation of all user inputs and code
- Rate Limiting: API rate limiting and execution time constraints
Performance Optimizations
- CRDT Efficiency: Y.js provides efficient conflict-free replicated data types
- Connection Pooling: WebSocket connection pooling and management
- Caching Strategy: Redis caching for session data and user presence
- Queue Management: AWS SQS for reliable job processing and scaling
