kafka集群非刷盘模式是否可以对某些主题生效？

Question

如果我想让Kafka集群支持准实时消息转换（< 500 ms), do I need to set the Kafka cluster to the non-flushing disk mode? If I set non-flushing disk mode, Whether non-flushing disk mode could takes effect for certain topics? not for all the topics, because other topic I need high reliability for consumers.

默认情况下，Kafka 在消息处理期间不会强制 fsync，您可以通过设置配置属性在主题级别更改它：

• flush.messages
• flush.ms
