## 1\. The Shift to Event-Driven Architecture

Modern software applications demand ultra-low latency and seamless horizontal scalability. Traditional synchronous REST APIs often introduce tight coupling and cascade failure points across microservices.

## 2\. Event Streaming Code Example

```typescript
interface StreamConfig {
  topic: string;
  partitions: number;
  replicationFactor: number;
}

async function createEventStream(config: StreamConfig): Promise<void> {
  console.log(`[Stream] Initializing topic: ${config.topic} with ${config.partitions} partitions`);
}
```

By utilizing distributed commit logs, services communicate asynchronously through immutable event streams, enabling true decoupled event-driven systems.

⚡ Pro Tip: Always partition message streams by domain entity ID to guarantee sequential processing order across consumer workers.

## 3\. Key Architectural Takeaways

Designing resilient systems requires accepting trade-offs between consistency, availability, and partition tolerance (CAP theorem). Always design for idempotency and fail-safe retries.
