In this chapter, you'll learn how Spark manages data and how can you read and write tables from Python.

What is Spark, anyway?

Using Spark in Python

Examining The SparkContext

Getting started with machine learning pipelines

In this last chapter, you'll apply what you've learned to create a model that predicts which flights will be delayed.

What is logistic regression?

Create the modeler

Cross validation

Create the evaluator

Make a grid

Make the validator

Fit the model(s)

Evaluating binary classifiers

Evaluate the model

In this course, you'll learn how to use Spark from Python! Spark is a tool for doing parallel computation with large datasets and it integrates well with Python. PySpark is the Python package that makes the magic happen. You'll use this package to work with data about flights from Portland and Seattle. You'll learn to wrangle this data and build a whole machine learning pipeline to predict whether or not flights will be delayed. Get ready to put some Spark in your Python code and dive into the world of high-performance machine learning!
