设置 acks = all。acks 是 Producer 的一个参数，代表了你对“已提交”消息的定义。如果设置成 all，则表明所有副本 Broker 都要接收到消息，该消息才算是“已提交”。这是最高等级的“已提交”定义。
|
|||
|
|
对于游戏日志，设置为WaitForLocal即可；如果是游戏数据，则应设置为WaitForAll
|
|||
|
|
设置 retries 为一个较大的值。这里的 retries 同样是 Producer 的参数，对应前面提到的 Producer 自动重试。当出现网络的瞬时抖动时，消息发送可能会失败，此时配置了 retries > 0 的 Producer 能够自动重试消息发送，避免消息丢失。
