Bringing it all together I
You've built a solid foundation in PySpark, explored its core components, and worked through practical scenarios involving Spark SQL, DataFrames, and advanced operations. Now it’s time to bring it all together. Over the next two exercises, you're going to make a SparkSession, a Dataframe, cache that Dataframe, conduct analytics and explain the outcome!
This exercise is part of the course
Introduction to PySpark
Exercise instructions
- Import
SparkSession
frompyspark.sql
. - Make a new
SparkSession
calledfinal_spark
usingSparkSession.builder.getOrCreate()
. - Print
my_spark
to the console to verify it's aSparkSession
. - Create a new DataFrame from a preloaded schema and column definition.
