Flatten nested dictionaries, compressing keys
...does the key-reducer function (which I hereby refer to as 'join') require access to the entire key-path, or can it just do O(1) work at every node in the tree? If you want to be able to say joinedKey = '_'.join(*keys), that will cost you O(N^2) running time. However if you're willing to say nextKey ...
What is the difference between map and flatMap and a good use case for each?
...g from a collection of lines to a collection of words looks like:
["aa bb cc", "", "dd"] => [["aa","bb","cc"],[],["dd"]] => ["aa","bb","cc","dd"]
The input and output RDDs will therefore typically be of different sizes for flatMap.
If we had tried to use map with our split function, we'd h...
