Issue

  • What did you do?

Used GroupBy method of dataframe

  • What happened?

Got GroupBy object. GroupBy object doesn't provide any easy way to iterate the groups and rows inside the group

  • What did you expect?

I expected ability to have API similar to GroupBy operation in LINQ with ability to iterate groups and DataFrameRows inside th group (having IEnumerable<IGrouping<out TKey, out TElement>> interface)
