Parallelized collections are produced by calling JavaSparkContext?�s parallelize system on an present Selection in the driver program.
This design and style allows Spark to run more efficiently. For example, we can easily know that a dataset designed by map might be Utilized in a decrease and return only the results of the lower to the driving force, as opposed to the bigger mapped dataset.
