Dask Bag [15] is an unordered collection of repeated objects, a hybrid between a set and a list. Dask Bag is used to parallelize computation of semi-structured or unstructured data, such as JSON records, text data, log files or user-defined Python objects using operations such as filter, fold, map and groupby.
The function to extract the key value from the object is specified by the user as a delegate. Reverse The Reverse operator reverses a collection.

That is, non-key attributes are functionally dependent on the superkey.
