ADF Data flow task writing to BLOB CSV

Mav 81 Reputation points


I am working on ADF data flow and writing to sink JSON CSV BLOB .
In my my SINK dataset config I am providing the name of the file that I want to be created
I am using dynamic config for filename ('FILENAME,utcnow())


However when data flow runs successfully, the file that is created in the container is of different name like highlighted in yellow below


Any ideas why the file name is different from the one mentioned in the dataset

    Hi @devhere ,
    Thankyou for using Microsoft Q&A platform and posting your question.
    In the sink transformation of your data flow, you need to change few things :
    1. Select FileName option as 'Output to single file' in Settings tab
    2. When you do that there there will be a recommendation popping up saying 'Output to single file' requires 'Single partition' . Click on Set single partition. You can also do this by selecting 'Set single partition' option in Optimize tab.
    3. Provide name of the output file in the option 'Output to Single file'

    Hope this will help. Please let us know if any further queries.
