Kafka
组件
基本概念
However, if you require a total order over records this can be achieved with a topic that has only one partition, though this will mean only one consumer process per consumer group.
?是否可以这样理解:一个kafka集群内的topic下存在多个partition,每个partition内的log是有序的。若一个topic存在多个partition,则同一个consumer group内的多个consumer不会同时消费相同的partition.
