Know what tools and prerequisites you need before Section 2

Welcome to the bootcamp

Over the next 18 sections you'll go from "I've heard of Spark" to confidently designing, building, tuning, and deploying real Spark pipelines that process data at massive scale. This is a hands-on, Python-first course built on Apache Spark 4.0 and PySpark — every concept is reinforced with runnable code, a guided exercise, or a lab, and the back half is built around full projects you can put on a résumé or GitHub.

You don't need any prior distributed-systems or Spark experience. If you're comfortable with Python and can read a SQL SELECT with a JOIN and a GROUP BY, you're ready.

The path you'll walk

The course is a ladder — each rung reuses and extends the skills from the last.

You'll climb from distributed-computing foundations to production-grade, deployed Spark pipelines.

Foundations — why Big Data exists, how clusters split work, and why Spark beats classic MapReduce.
Core APIs — RDDs for low-level control, then the DataFrame API and Spark SQL for real analytics.
Scale & speed — every major file format, joins and shuffles, performance tuning, and Structured Streaming.
Production — the Delta lakehouse, MLlib, cloud and Kubernetes deployment, Kafka, orchestration, and five capstone projects.

How the course is organized

The roadmap moves deliberately from fundamentals to full applications:

Phase	Sections	What you'll be able to do
Foundations	1–4	Reason about distributed systems, Spark's architecture, and stand up a Spark 4.0 environment
Core APIs	5–8	Build pipelines with RDDs, DataFrames, and Spark SQL
Data & performance	9–13	Read every format, tune joins/shuffles, stream data, and test pipelines
Production	14–18	Deploy to cloud/K8s, build a lakehouse, train ML models, and ship capstones

How to use the labs and projects

Don't just read the code — run it. Open a notebook or the PySpark shell and follow along. Each section ends with a short quiz so you can confirm the ideas stuck before moving on, and the projects (marked in their titles) are where the skills become muscle memory.

What you'll need

You'll set all of this up in Section 4 — nothing to install yet, just know what's coming:

Java 17 — Spark 4.0 runs on the JVM and requires a modern JDK.
Python 3.11+ and PySpark 4 in a virtual environment.
Docker — for a reproducible local Spark cluster you'll reuse all course.
A code editor such as VS Code, or Jupyter for interactive work.

Lesson Summary

This course is a hands-on, Python-first journey through Apache Spark 4.0 — from distributed-computing foundations to production deployment and capstone projects. Run the code as you go, take the quizzes, and build the projects. Next up: what "Big Data" actually means.
