# v1.7.0 - 消息队列

## Kafka集成

```go
// 生产者
producer, _ := kafka.NewProducer(&kafka.ConfigMap{
    "bootstrap.servers": "localhost:9092",
})

producer.Produce(&kafka.Message{
    TopicPartition: kafka.TopicPartition{Topic: "messages"},
    Value:          msgBytes,
}, nil)

// 消费者
consumer, _ := kafka.NewConsumer(&kafka.ConfigMap{
    "bootstrap.servers": "localhost:9092",
    "group.id":          "message-processor",
})

consumer.Subscribe("messages", nil)
```

## 事件驱动架构

```go
// 事件处理器
type EventHandler struct {
    handlers map[string]func(event Event)
}

func (h *EventHandler) Handle(event Event) {
    if handler, ok := h.handlers[event.Type]; ok {
        handler(event)
    }
}
```
