Azure Stream Analytics: File name prefix

While using ADLS Gen 1 as output for a Stream Analytics job, if the file path pattern doesn't contain a trailing slash (/), the last pattern in the file path is treated as a file name prefix.
For example, if the path pattern is 'dir/{date}/{time}' the file created is 'dir/2021/03/30/00_filename.json'.
However, applying the same logic with an ADLS Gen 2 output the time variable is treated as a regular directory: 'dir/2021/03/30/00/filename.json'.
Is there a way to specify the file name prefix in an ADLS Gen 2 output?

    Hi @Aris Konomis ,

    I have received confirmation from products team that this behavior is by design. Could you please provide this as a feature request at Azure Stream Analytics Uservoice so that community can upvote and the product team can plan to include in future releases.

    Thanks
    Saurabh
