   We create the data using Spark 3.1 currently. Specifically many of the 
feature processing algorithms of SparkML produce vector columns as outputs 
which we proceed to convert to plain Python float lists and save to parquet. 
Depending on the parallelism we choose for Spark we can end up in the above 
situation. I'm not sure if we can explicitly use LargeList to save our data, is 
there a pyarrow API for that?
