    小哥还是做了挺多工作的，很棒，最后conclusion没提到还是没听清，MongoDB有错误注入是不符合cc？
  • 在有错误注入的情况下，想要符合cc需要将write concern和read concern都设置为majority
  • 虽然已经知道MongoDB now recommends using both read concern majority and write concern majority to preserve causal guarantees and durability across all failure scenarios。
    Causal guarantees are anything but casual — The MongoDB Engineering Journal ，赞小哥。
