The Definitive Guide to Data Quality
so if I understand correct the output column name cannot be the same as the input column name?
Suppose I have only 1 input column (name1 for example) and 1 output column(name2 for example) on the tDenormalize component, with different names as mentioned, then I get an error in talend when i run this saying that 'name1 cannot be resolved or is not a field'.
but of type List and add 'myColumn' in the 'To denormalize' list, then it seems my rows are combined in this list(and the output is 1 row),
so the documents (left side of scheme) are ending up in the list (right side of scheme).
