MongoDB（Wired tiger）：向上插入错误，并使用；重复密钥错误"；-多线程

在

mongodb

中执行

upsert

时，我在应用程序中遇到了以下错误：

搜索后，我们发现JIRA中有两个未决问题：

注意：我们的应用程序是多线程的。两个不同的线程正在执行批量升级

为了避免失败并用正确的值更新文档，在应用程序端用Java编写代码的替代方法是什么？

。由于这似乎只适用于WT（），因此一种简单的方法是更改存储引擎，在由副本集支持的副本集/分片集群中，应该可以不停机。根据Java方面：您必须在要写入的对象上进行同步，这对于一个bug来说是一个奇怪的解决办法。感谢更新…@MarkusWMahlberg..因为我们的代码是集群的（两台不同机器上的应用程序的两个实例），所以同步不会解决Java方面的问题..还有其他选择吗？
