Perform Operation on only one column External filter stage

Post by chetan.c »

Hi,

I have two input columns
col1 col2
Data Filename

In the external filter stage i am calculating byte size of col1.

I want my output to be
Col1 Col2
Byte_size(Data) Filename

In the external filter stage is it possible to perform operation only on one column?

Thanks,
Chetan.C
