@Pawel Automatically format files will assume the below, so if your file format is CSV, it is recommended you do not use this feature as you can always get a different line or field delimiter. Also, have you considered Dremio’s COPY INTO feature to move to Iceberg format?
The issue is that once I test this using csv file witch should be ok with this conf it never works correctly with automatically format (always only one column instead two in my example). But when I use the same csv file with set format process without any changes on GUI is working correctly.
So looks like issue with automatic formatting as couldn’t make it working with any csv version.
Could you check that and give me simple example of working csv file format with this automatically option ?
