TupleTarget

[gabrielgonzaga]

Define a way to create tuple targets. E.g.

Say my task creates an encoder, and I want to return the encoding object and the transformed data frame:

@inherit_list(ETLTask)
class EncodeCat(Task):
target_type = PickleTarget, ParquetTarget

def easy_run(self, inputs):
    df = inputs[0]
    df, encs = encode_func(df)
    return df, encs

One would be a Pickle and the other a Parquet

This is against Luigi idea. Basically it is "one task, one output"

we could handle that on that "complete"method to guarantee that all targets are there. maye it is a good feature.

Yes, I was thinking st. like that, make sure this kind of target deals correctly with all .complete Targets inside it
