原答案：難道不是topic的擴充能力嗎？不然單topic的容量只能限制在實體機上了 更新後的答案： The partitions in the log serve several purposes. First, they allow the log to scale beyond a size that will fit on a single server. Each inpual server. Eachitionpual partition must fit on the servers that host it, but a topic may have many partitions so it can handle an arbitrary amount of data. Second they act as the unit of parallelism—more on that in a bit。 。 partitions 主要有兩個目的，1 增強擴展能力，讓其可以處理任意多的資料 2 作為並行單元，提高並行能力（主要鑑於此點考慮）。 第一次回答我只記得第一點了~~sorry
