How can we have at the end the same schema as the original schema? By exploding the "row_key" column thanks to a PERL regular expression?
This component allows to split the "row_key" but it doesn't allow to load the "pivot_key" and the "pivot_value" and it doesn't support 2 outputs..
How can we split the "row_key" and then load all the columns (with "pivot_key" and "pivot_value")? With a TMap ?
