Subject Re: Difference between Data set and Data Frame in Spark 2
Date Thu, 01 Sep 2016 14:26:02 GMT
Here's my paraphrase:

Datasets are really the new RDDs. They have a similar nature
(container of strongly-typed objects) but bring some optimizations via
Encoders for common types.

DataFrames are different from RDDs and Datasets and do not replace and
are not replaced by them. They're fundamentally for tabular data, not
arbitrary objects, and thus supports SQL-like operations that only
make sense on tabular  data.
