背景: 空气流利用Alembic将移民应用到其储存DAG/task元数据所使用的数据库。 我想在这个数据库中储存一些其他数据,并希望通过阿莱芒语移民跟踪我的图象变化。 可以假定,我的移徙将限于创建/修改新的表格,而不会改变空气流产生和使用的任何表格。
两套移民(航空源代码一,适用法一)是否引起任何问题?
Even if you use the same DB server, I suggest to use a different schema/database for the applicative stuff.
This way, when you pass a connection string in the env.py that runs the migrations, it will use a different alembic_version table and therefore they wouldn t collide.
如果你可以单独提出一个图象,那么你可以在你适用法的文稿/文稿模块中确定背景组合中的“转化——稳定”论点,给你一个单独的申请移民表格。
