Maximilian Michels commented on FLINK-3655:
-------------------------------------------
Sounds good. It is important to maintain backwards compatibility.
I'm not sure about the "comma-separated Path string". File names may contain
commas. So we might skip that for now and do the path list first.
I think we could also use {{readFile(FileInputFormat<X> inputFormat, String..
filePaths}} which will return the filePath as a {{String[] filepaths}} array.
> Allow comma-separated or multiple directories to be specified for
> FileInputFormat
