I have several columns that I am combining using data preparation recipe - and the 'nest' functionality. A number of these columns are in pairs and I am nesting them into a third column.
E.g: a1,b1 nested (in that order) to a1_b1, a2,b2 nested to a2_b2 and so on. Thus the map object created should be a1 and then b1.
However, an issue I face is for certain column pairs, the ordering is not maintained. i.e. when nested, the b column comes before a though the selection is first a and then b. The issue seems to affect in a random fashion.
Inputs;
a b
1 2
Outputs:
{"b": 2, "a": 1}
Is this a bug or am I missing something?
