DataStream API in Batch Execution mode

[Marco Villalobos-2]

How do I use a hierarchical directory structure as a file source in S3 when using the DataStream API in Batch Execution mode?

I have been trying to find out if the API supports that, because currently our data is organized by years, halves, quarters, months, and but before I launch the job, I flatten the file structure just to process the right set of files.

That worked.  Thank you very much.

Hi, Macro

I think you could try the `FileSource` and you could find an example from [1]. The `FileSource` would scan the file under the given directory recursively.

Would you mind opening an issue for lacking the document?

Best,
