Question

尝试使用SQL Server作为后端来设置气流，但在initdb命令中陷入困境：

在这里它永远挂着。

我查看为此创建的空数据库，并找到创建两个连接的过程，一个正在等待，另一个被另一个锁定：

exec sp_who;

spid    ecid    status  loginame    hostname    blk dbname  cmd request_id
55  0   sleeping    TestServiceUser my_server   airflow AWAITINGCOMMAND 0
56  0   suspended   TestServiceUser my_server   55  airflow EXECUTE 0'

要求SQL Server创建“所有阻止的事务”报告将返回以下结果：

会话55正在使用SQL语句阻止：-
  会话56被阻止完成：

选择前1个slot_pool.id作为slot_pool_id，
                  slot_pool.pool为slot_pool_pool，
                  slot_pool_slots，
                  slot_pol.description作为slot_pool_description，
     来自slot_pool
     其中slot_pool.slots = 1 AND slot_pool.pool = N'default_pool

我尝试取消阻止连接，但这会导致错误。

我也尝试过使用自动提交和池大小，但是无法使其超过最后一行。

您知道什么可能会继续阻止吗？

apache-airflow（1.10.5）
Python 3.6.8
SQL Server 2016（v13.0.5264.1）
