I have a question want study from you.
when we load data from a excel table. I don't need all column to qvw file, there have a 2 method for my understand.
first, remove column by transformation step in "File wizard"; second, just keep useful column name in load script.
what's the different or not? my focus on if well impact memory in qvw or load efficiency.
thanks a lot!
If you take required columns then it will improve your performance because its in memory tool. Its Store your all data on server memory means less data less memory.
