What is a map style Dataset?
Map-style datasets give you their size ahead of time, are easier to shuffle, and allow for easy parallel loading. It’s a common misconception that if your data doesn’t fit in memory, you have to use iterable-style dataset. That is not true. You can implement a map-style dataset such that it retrives data as needed.
