使用实体框架核心的MS DTC取消交易

我收到一个

System.Data.SqlClient.SqlException（0x80131904）：Microsoft分布式事务处理协调器（MS DTC）已取消了分布式事务处理。

使用EF Core 2.1时出现

错误。完整的堆栈跟踪位于此消息的底部。

这是基本过程：

  1. 从Kafka读取请求消息
  2. 将消息写到SQL Server上的一组“原始”表中
  3. 调用存储过程，该过程从原始表中读取消息，验证传入的数据，转换数据中的几个字段，然后写入一组“生产”表。
  4. 从生产表中检索转换后的请求。
  5. 通过主要是微服务的业务流程处理请求，并随着业务流程的进展将更新保存回生产表。

MSDTC错误在步骤3间歇性但频繁发生。步骤2和3中的原始表和生产表位于同一SQL Server上的单独数据库中。作为第5步的一部分，还有一个对单独的SQL Server的调用，但我得到的唯一错误是在第3步期间取消了MSDTC。

我知道.NET Core不支持MSDTC，但是我不确定为什么将此过程的这一部分提升为MSDTC。我没有任何显式事务，并且通过appsettings中的ConnectionStrings为每个数据库标准化了连接字符串。

任何见识表示赞赏。

答案 0 :(得分：0)

事实证明这是一条红鲱鱼。我读过某个地方的MSDTC问题有时掩盖了其他问题，建议进行数据库跟踪。可以肯定的是，跟踪显示在负载下临时表正在通过连接删除，因此我们现在正在努力解决此问题。
