我有一个关于 sarama Go 语言 Kafka 库的看似简单的问题：当 Kafka 代理由于空闲超时（由connections.max.idle.ms配置控制）而关闭时，生产者是否应该在/通过发送新消息时自动重新建立与代理的连接消息与否？
我无法在我检查的任何资源中找到答案：
我问是因为它似乎没有自动重新连接 - 现在我应该尝试避免超时（通过增加connections.max.idle.ms配置或发送心跳消息）还是应该提出 sarama 的问题？
我还查看了 sarama 日志以获取有关此处实际发生的情况的线索（测试场景，每 10 分钟发送一次消息）但是，对于 Kafka 和 Go 来说都是新手，我无法从中获得太多收益：
