Current Refactoring Context

Data Ingestion Service Refactor

The project is currently undergoing a major refactoring to move away from singleton patterns to a dependency injection approach using service containers.

What's Been Done

• Created connection pool pattern with ServiceContainer
• Refactored data-ingestion service to use DI container
• Updated handlers to accept container parameter
• Added proper resource disposal with ctx.dispose()

Migration Status

• QM handler: ✅ Fully migrated to container pattern
• IB handler: ⚠️ Partially migrated (using migration helper)
• Proxy handler: ✅ Updated to accept container
• WebShare handler: ✅ Updated to accept container

Key Patterns

1. Service Container: Central DI container managing all connections
2. Operation Context: Provides scoped database access within operations
3. Factory Pattern: Connection factories for different databases
4. Resource Disposal: Always call ctx.dispose() after operations

Example Pattern

const ctx = OperationContext.create('handler', 'operation', { container });
try {
  // Use databases through context
  await ctx.mongodb.insertOne(data);
  await ctx.postgres.query('...');
  return { success: true };
} finally {
  await ctx.dispose(); // Always cleanup
}

Next Steps

• Complete migration of remaining IB operations
• Remove migration helper once complete
• Apply same pattern to other services
• Add monitoring for connection pools
