Azure SQL DMS 内部的 DW 死锁
Azure SQL DW deadlock inside DMS
我们在 DMS 内部遇到死锁，至少有 30% 或更多的时间发生在几个较大的存储过程上，这些存储过程 运行 处理并插入数百万行。但是，只有一个查询 运行ning，所以我不明白死锁怎么会是我的错：
Msg 110802, Level 16, State 1, Line 1

这一点是否明显需要检查或修复？还是 Azure 支持案例是解决问题的最佳途径？
更新：支持案例 115111713384329 已针对此问题开放
更新：我们的 SQL DW 在 2016 年 3 月 4 日获得了一个新的更新，据说可以解决这个问题。 （我无法按需复制它，所以我不能肯定地说。）如果你 运行 "select @@version" 那么
10.0.8224.5 或更高版本应该有修复。如果您还没有修复，我会想象打开一个支持案例并请求它或等待几周会给您修复。
在这种情况下最好创建一个 Azure 支持案例。如果您可以分享您的存储过程，那将有助于我们找到根本原因。
