  1 Apache Spark Lab Objective: Dealing with massive amounts of data often requires parallelization and cluster computing; Apache Spark is an industry standard for doing just that. In this lab we introduce the basics of PySpark, Spark’s Python API, including data structures, syntax, and use cases. Finally, we

  A normal NumPy array knows its shape, a dask array must know its shape and the shape of all of the internal NumPy blocks that make up the larger array. These shapes can be concisely described by a tuple of tuples of integers, where each internal tuple corresponds to the lengths along a single dimension.
