Why this course?

Description

Apache Spark has become the industry standard for big data processing and analytics. From batch processing to real-time streaming, Spark powers the data infrastructure of top technology companies worldwide. If you’re aiming for a career as a Data Engineer, Big Data Developer, or preparing for the Databricks Spark Certification, mastering Spark with Scala is one of the most valuable skills you can acquire today.

This course is a comprehensive, beginner-to-advanced guide to learning Apache Spark with Scala, designed with a strong focus on hands-on practice, real-world use cases, and certification readiness. Unlike many theory-heavy courses, here you’ll actively work with Spark from day one — exploring its architecture, execution flow, transformations, and actions through live coding and demonstrations.

What You’ll Learn in This Course

Fundamentals of Spark and Cluster Architecture

• Understand the core building blocks: driver, executors, partitions, jobs, stages, and tasks.
• Learn how Spark distributes workloads across a cluster and optimizes execution.
• Set up and provision a Spark cluster in Databricks, giving you cloud-ready skills.

 

Working with Databricks & Notebooks

• Learn how to create a free Databricks account.
• Explore notebooks, clusters, and collaborative features in Databricks.
• Get tips and tricks to maximize your learning experience while practicing on real Spark environments.

 

Spark SQL, DataFrames, and Datasets

• Create and manipulate RDDs, DataFrames, and Datasets with Scala.
• Work with structured and semi-structured data sources including CSV, JSON, Avro, Parquet, LIBSVM, and image files.
• Write SQL queries programmatically using Spark SQL APIs.
• Use built-in scalar functions, user-defined functions (UDFs), and optimize queries using caching and persistence.

 

RDD Transformations and Actions

• Master key transformations: map, filter, flatMap, groupBy, reduceByKey, join, and more.
• Understand the difference between narrow vs. wide transformations and their performance impact.
• Apply common Spark actions: collect, count, take, reduce, foreach, and more.
• Learn the concept of shuffling and how it impacts performance in distributed computing.

 

Advanced Spark Features

• Optimize your applications with persistence, cache, and unpersist.
• Use broadcast variables and accumulators for performance tuning.
• Explore Spark execution internals to better understand how jobs are broken down and executed across nodes.

 

Why Take This Course?

• Beginner-Friendly, Yet In-Depth – No prior Spark experience is required. We start with basics and gradually move to advanced topics, ensuring learners at all levels benefit.
