【问题】 请问 "出入队严格有序" 这一个feature指的是 全局队列有序 还是指 单一队列(我的理解就是一个Store)的出入严格有序?如果是后者,要满足全量数据严格有序的话 producer 在入队列的时候就需要做数据倾斜(例如 通过key来约束)? 谢谢~

你好, 从Store的角度来看单一队列是出入严格有序的,因为一条队列只归属于一个Paxos Group; 但是从Consumer的角度来看默认是相同key出入严格有序,因为Consumer有批量处理特性,其中相同key的数据保证串行处理,不同key的数据会并发处理,这是提高消费效率的一个特性;如果关掉这个特性,那从外部看来,就是单一队列出入严格有序的。
Sorry, something went wrong.
@unixliang 感谢你详细清晰解释~
