PySpark Learning Handbook with Kaibalya Biswal

PySpark is no longer optional for data professionals working at scale. It's expected.

This resource cuts through the noise and gives you exactly what you need to go from PySpark beginner to someone who can confidently build and run distributed data pipelines.

Core topics covered:

1. Spark architecture — what actually happens under the hood.
2. Setting up PySpark locally and on the cloud.
3. DataFrames, schemas & column operations.
4. Grouping, filtering, joining & window functions.
5. Working with real datasets end to end
6. Writing production-ready PySpark code

Built for:

1. Data Analysts ready to level up.
2. ML practitioners dealing with big data pipelines.
3. Engineers transitioning into Data Engineering roles.

The goal isn't to make you memorize syntax. It's to make you think like someone who builds at scale.
