My Dataflow is writing data to a delimited text sink; the file naming pattern looks like this:
When the files are ultimately written out to ADLS, the file names look like this:
I can't find any documentation on where the "-00001" is coming from. Does anyone know, and more importantly, how to turn it off?
Thanks.
I have reprod the same error what you are getting by keeping the same Sink settings as per you.
My Sink setting looks like in below snippet.
My Parameter value is shown below.
You also need to have a look into Sink’s Optimize tab where you will be able to see the Partition option. For File name option as Pattern under Setting tab, Partition option will be by default Use current partitioning.
Now, this is how my Sink data looks like in Storage after running the pipeline.
To resolve this issue, under Setting tab keep File name option as Output to single file and under Optimize tab, keep Partition option as Single Partition. Refer below images for the same.
Now, when you run your data flow, the single file will be created with the same name as of your parameter.
