   > 这个问题发生在syncStateSet扩张时刻，本地的syncStateSet和远程syncStateSet不一致的时候，如何决定ack数保证消息不丢。
   > 按照这个要求， 不管是syncStateSet的收缩或者扩张，
   
   是的, 我的思路是同步数据时新增一个状态判断是否正在同步新的 SyncStateSet 给 Controller (IsSynchronizing syncstateset), 是的话取本地和远程的 Syncstateset 合集.
   
   另一种方案是直接 Hold 住写请求, 等 syncstateset 修改完之后再继续, 但是性能有影响 @ShannonDing
