Analyze an Apache Spark DataFrame as though it were a relational database table. During this Aspire course, you will discover the different stages involved in optimizing any query or method call on the contents of a Spark DataFrame. Discover how to create views out of a Spark DataFrame's contents and run queries against them; and how to trim and clean a DataFrame. Next, learn how to perform an analysis of data by running different SQL queries; how to configure a DataFrame with an explicitly defined schema; and define what a window is in the context of Spark. Finally, observe how to create and analyze categories of data in a data set by using Windows.

WHAT YOU WILL LEARN

  • Recall the different stages involved in optimizing any query or method call on the contents of a spark dataframe
    Create views out of a spark dataframe's contents and run queries against them
    Trim and clean a dataframe before a view is created as a precursor to running sql queries on it
    Perform an analysis of data by running different kinds of sql queries, including grouping and aggregations
  • Recognize how spark dataframes infer the schema of data loaded into them and configure a dataframe with an explicitly defined schema
    Define what a window is in the context of spark dataframes and when they can be used
    Create and analyze categories of data in a dataset using windows
