They are the same. These are just different ways to construct catalyst

Is it correct to say that Spark Dataframe APIs are implemented using same
execution as SparkSQL ? In other words, while the dataframe API is
different than SparkSQL, the runtime performance of equivalent constructs
in Dataframe and SparkSQL should be same. So one should be able to choose
whichever of the two (DF v/s SQL) suite the use cases and not worry about
runtime performance.
