quintillion bytes of data are created every single day, and it’s only going to grow from there. Also, there is no interactive mode available in MapReduce Spark has APIs in Scala, Java, Python, and R for all basic transformations and actions. It also supports multiple languages and has APIs for Java, Scala, Python, and R.

Each file has a 150 byte cost in NameNode memory, and HDFS has a limited number of overall IOPS. repartition(5*365, $”date”, $”rand”) Under the hood, Scala will construct a key that contains both your date, and your random factor, something like (<date>, <0–4>). However, there is a cost.
