> Affects Versions: 1.6.2, 1.7.0, 1.7.1, 1.7.1.2, 1.7.1.3, 1.8.0, 2.0.0
> Environment: Airflow Environment:
> Distributor ID: Ubuntu
> Description: Ubuntu 14.04.5 LTS
> Release: 14.04
> Codename: trusty
> Backend:
> SQL Server 2012 SP3
> Reporter: Chad T Henderson
> Assignee: Chad T Henderson
> Priority: Major
>
> When trying to run initdb for a MS-SQL 2012 backend, my the alembic
> migrations freeze almost immediately.
> After querying the database for blocking queries, I discovered that this
> query:
> CREATE TABLE alembic_version (
> version_num VARCHAR(32) NOT NULL
> )
>
> was blocking this query.
> SELECT [INFORMATION_SCHEMA].[TABLES].[TABLE_NAME]
> FROM [INFORMATION_SCHEMA].[TABLES]
> WHERE [INFORMATION_SCHEMA].[TABLES].[TABLE_SCHEMA] = CAST('dbo' AS
> NVARCHAR(max)) AND [INFORMATION_SCHEMA].[TABLES].[TABLE_TYPE] = 'BASE TABLE'
> ORDER BY [INFORMATION_SCHEMA].[TABLES].[TABLE_NAME]
> I attempted to let the migrations run for ~45 minutes (multiple times) and it
> did not appear that the blocking was going to resolve itself.
> Each query was running under a separate session, which is what I believe is
> the cause of the blocking.
