要创建所需的目标表,可以在增量实时表 Python 接口中使用create_streaming_table()函数。 Python复制 apply_changes_from_snapshot( target ="<target-table>", source = Any, keys = ["key1","key2","keyN"], stored_as_scd_type = <type>, track_history_column_list =None, track_history_except_...
若要在 Azure 中创建函数应用时请求特定的 Python 版本,请使用 az functionapp create 命令的 --runtime-version 选项。 函数运行时版本由 --functions-version 选项设置。 Python 版本是在创建函数应用时设置的,不能为在消耗计划中运行的应用更改它。 运行时在本地运行时使用可用的 Python 版本。 更改Python 版本...
We will use python's list comprehensions to create lists of the attribute columns in the DataFrame, then print out the lists to see the names of all the attribute columns. sdf_target_cols = [column for column in sdf_target.columns] sdf_join_cols = [column for column in sdf_join.columns...
You can also create Python functions in the Azure portal. Tip Although you can develop your Python-based Azure functions locally on Windows, Python is supported only on a Linux-based hosting plan when it's running in Azure. For more information, see the list of supported operating system/run...
