谢谢！更新后应该更贴近原文的表述：

If asynchronous replication is used, the new leader may not have received all the writes from the old leader before it failed. If the former leader rejoins the cluster after a new leader has been chosen, what should happen to those writes? The new
leader may have received conflicting writes in the meantime. The most common solution is for the old leader’s unreplicated writes to simply be discarded, which may violate clients’ durability expectations.
