20240101000012_create_additional_indexes.sql	Performance optimization	60+ indexes (B-tree, GIN, composite)

2. Total Objects Created

• 18 Tables: All core Attune data models
• 11 Enum Types: Type-safe status and category enums
• 100+ Indexes: B-tree, GIN (JSONB/arrays), and composite indexes
• 20+ Triggers: Auto-update timestamps, validation, notifications
• 5+ Functions: Validation logic, pg_notify handlers
• Constraints: Foreign keys, check constraints, unique constraints

3. Key Features Implemented

Automatic Timestamp Management

• All tables have created and updated timestamps
• Triggers automatically update updated on row modifications

Reference Preservation

• *_ref columns preserve string references even when entities are deleted
• Enables audit trails and historical tracking

Soft Delete Support

• Foreign keys use ON DELETE SET NULL for historical preservation
• ON DELETE CASCADE for true dependencies

Validation Constraints

• Lowercase reference validation
• Format validation (pack.name patterns)
• Semantic versioning validation for packs
• Owner validation for keys
• Port range validation

Performance Optimization

• B-tree indexes on frequently queried columns
• GIN indexes on JSONB columns for fast JSON queries
• GIN indexes on array columns
• Composite indexes for common query patterns
• Strategic partial indexes for filtered queries

PostgreSQL Features

• JSONB for flexible schema storage
• Array types for multi-value fields
• Enum types for constrained values
• Triggers for data validation
• pg_notify for real-time notifications

4. Documentation

• ✅ migrations/README.md: Comprehensive migration guide
  • Running migrations (SQLx CLI and manual)
  • Database setup instructions
  • Schema overview
  • Troubleshooting guide
  • Best practices

5. Tooling

• ✅ scripts/setup-db.sh: Database setup automation script
  • Creates database
  • Runs migrations
  • Verifies schema
  • Supports both SQLx and manual execution
  • Configurable via environment variables

Database Schema Overview

Testing Instructions

1. Create Database and Run Migrations

# Option 1: Use the setup script (recommended)
./scripts/setup-db.sh

# Option 2: Manual setup
createdb attune
export DATABASE_URL="postgresql://postgres:postgres@localhost:5432/attune"
sqlx migrate run

# Option 3: Manual with psql
createdb attune
for file in migrations/*.sql; do
    psql -U postgres -d attune -f "$file"
done

2. Verify Schema

# Connect to database
psql -U postgres -d attune

# Check schema exists
\dn attune

# List all tables
\dt attune.*

# List all enums
\dT attune.*

# Check specific table
\d attune.pack

# Verify indexes
\di attune.*

# Check triggers
SELECT * FROM information_schema.triggers WHERE trigger_schema = 'attune';

3. Test Basic Operations

-- Insert a test pack
INSERT INTO attune.pack (ref, label, version, description)
VALUES ('core', 'Core Pack', '1.0.0', 'Core automation components');

-- Verify created/updated timestamps
SELECT ref, created, updated FROM attune.pack;

-- Test update trigger
UPDATE attune.pack SET label = 'Core Pack Updated' WHERE ref = 'core';
SELECT ref, created, updated FROM attune.pack;

-- Verify constraints
INSERT INTO attune.pack (ref, label, version)
VALUES ('INVALID', 'Test', '1.0.0'); -- Should fail (uppercase ref)

INSERT INTO attune.pack (ref, label, version)
VALUES ('test', 'Test', 'invalid'); -- Should fail (invalid semver)

-- Test foreign key relationships
INSERT INTO attune.action (ref, pack, pack_ref, label, description, entrypoint)
VALUES ('core.test', 1, 'core', 'Test Action', 'Test', 'actions/test.py');

-- Test cascade delete
DELETE FROM attune.pack WHERE ref = 'core';
SELECT COUNT(*) FROM attune.action; -- Should be 0

-- Clean up
DELETE FROM attune.pack;

Next Steps: Phase 1.2 - Repository Layer

Now that the database schema is complete, the next step is to implement the repository layer:

Tasks for Phase 1.2

1. Create Repository Module Structure

   • crates/common/src/repositories/mod.rs
   • Individual repository modules for each table

2. Implement Repository Traits

   • CRUD operations
   • Query builders
   • Transaction support

3. Write Repository Tests

   • Unit tests for each repository
   • Integration tests with test database

Estimated Timeline

• Repository implementation: 1-2 weeks
• Testing: 3-5 days
