我正在尝试使用azure数据工厂v2读取最新的blob文件(csv)。文件名还包含日期(YYYY-MM-DD mm:ss-abcd.csv)。我需要从最新的文件中读取数据并加载到表存储中。您能帮我如何使用ADF读取最新文件

你好Faiz Rahman,谢谢你的提问。您选择的日期格式具有字典编排匹配和时间排序的有用功能。这意味着,一旦有了斑点列表,就需要提取日期并进行比较。
如果斑点列表很大,这可能不切实际。在这种情况下,每当您编写一个新的Blob时,都要在某个地方跟踪它,例如“ maxBlobName.txt”,并让管道读取该文件以获取最新文件的名称。
这是一些示例示例,用于比较Blob名称的日期部分。为了适应您的目的,您将需要使用GetMetadata活动来获取Blob名称,并使用一些字符串函数来仅提取名称的日期部分以进行比较。
