    The entry point to programming Spark with the Dataset and DataFrame API.

    In environments that this has been created upfront (e.g. REPL, notebooks), use the builder to get an existing session:

    SparkSession.builder().getOrCreate()

    The builder can also be used to create a new session:

    SparkSession.builder
  .master("local")
  .appName("Word Count")
  .config("spark.some.config.option", "some-value")
  .getOrCreate()
