> 这个pr的目的是让选中的broadcast join node 生成rf. 但为了避免选中的node 正好是最慢的,所以会多选几个node生成rf. 所以是否可以考虑另一个方案: 所有join node都生成rf, 当rf manager收到一个 rf时就通知其他node 停止生成rf 这样有两个负面因素： 1. 所有be都生成rf，浪费cpu计算 2. be引入了更复杂的状态控制，这里各种通知涉及到分布式多机交互和pipeline task的状态，会比纯规划方案风险大很多 -- This is an automated message from the Apache Git Service.
