Apache Spark End-To-End Data Engineering Project | Apple Data Analysis

Dive into the world of big data processing with our PySpark Practice playlist. This series is designed for both beginners and seasoned data professionals looking to sharpen their Apache Spark skills through scenario-based questions and challenges.

Each video provides step-by-step solutions to real-world problems, helping you master PySpark techniques and improve your data-handling capabilities. Whether preparing for a job interview or just learning more about Spark, this playlist is your go-to resource for practical, hands-on learning. Join us to become a PySpark expert!

In this video, we used DataBricks to create multiple ETL pipelines using the Python API of Apache Spark i.e. PySpark.

We have used sources like CSV, Parquet, and Delta Table then used Factory Pattern to create the reader class. Factory Pattern is one of the most used Low-Level designs in Data Engineering pipelines that involve multiple sources.

Then we used PySpark DataFrame API and Spark SQL to write the business transformation logic. In the loader part, we have loaded data into two fashion one using DataLake and another by Data LakeHouse.

While solving the problems, we are also demonstrating the most asked PySpark #interview problems. We have discussed and demonstrated a lot of concepts like broadcast join, partition by and bucketing, sparkSession, windows functions like LAG and LEAD, delta table and many other concepts.

After watching, please let us know your thoughts,

Stay tuned to all to this playlist for all upcoming videos.
