写入行时 Azure ADF DataFlow 失败

Question

I have dataflow in Azure Data Factory which convert parquet files into csv. It works when I have 10 files with a size of 10 KB. But if I have 3 files with a size of 22 KB there is an error 'failed while writing rows'.

Do you know what is possible solution?

Answer 2

Parquet file standard does not allow certain special characters. Use select transform or sink transform to remap these columns to different names. You can do it generically using pattern matching to rename all such columns also.
