I'm using Azure Data Factor data flow to save the incoming data as partitioned *.parquet files (Year/Month). I'm using the pattern setting for names of the files, as shown in the screenshot below. ADF automatically appends "00001" to the file name which I don't need because I use an expression to generate the file name, e.g. "Sales Date=2021-08-07-00001". The Optimize tab is set to Key partition type.
Is there any way to remove the '00001" suffix in the file name?
