Best way to get pieces of a parquet into a dataframe


#1

I’m looking for a minimal working example for loading some part of a parquet file into a dataframe and vice versa. I’m assuming that the only way to do this currently is with Spark.jl.

Right now I don’t even know if there is a quick and easy way of writing an example parquet as I don’t see how to convert a DataFrame into a Spark Dataset.
