Main Ideas and Concepts

Importance of Data Engineering

• AI adoption is booming, but AI depends on clean, structured, and reliable data.
• Data engineers build and maintain the systems that enable this.
• The big data market is rapidly growing—from $349B in 2023 to a projected $1.2T by 2032.
• Data engineering salaries range widely, up to $500K+ in the US and 1 crore+ in India.

Roadmap Overview

The roadmap covers 11 critical topics:

1. Programming Languages
2. Databases
3. Linux
4. Processing (Spark & Kafka)
5. Data Modeling & Data Warehousing
6. Orchestration (Airflow, Prefect, Mage, Daxter)
7. Cloud (AWS, Azure, GCP)
8. Git
9. DevOps
10. CI/CD
11. Projects

Detailed Breakdown and Methodology

1. Programming Languages

• Focus: Python (preferred for its ecosystem and simplicity)
• Write Pythonic code (use list comprehensions, built-in functions like zip, avoid C-style coding).
• Resources:
  • Python Cookbook (selective reading)
  • Fluent Python (for idiomatic Python)
  • Corey Schafer’s YouTube Python tutorials (cover basics up to OOP, skip Flask/Django initially)
  • Dr. Fred Baptiste’s deep-dive Python courses (4 parts, 22-46 hours each)
• Interview Prep: Focus on Data Structures & Algorithms (DSA) relevant to data engineering:
  • Arrays, strings, linked lists, stacks, queues, binary search, recursion, basic dynamic programming, sliding window.
  • Solve easy-medium problems on LeetCode and use resources like “Striver’s A2Z DSA Sheet” and MyCodeSchool channel (C++ explanations, supplement with Python code).

2. Databases

• Strong grasp of relational and one NoSQL database (e.g., MongoDB).
• Understand SQL vs NoSQL use cases.
• Core DBMS concepts: ACID properties, keys (primary, surrogate, foreign), normalization/denormalization, OLAP vs OLTP, indexing, partitioning.
• SQL mastery is critical: SELECT, JOIN, GROUP BY, aggregation, CTEs, window functions, subqueries, CASE WHEN inside aggregations.
• Practice medium-hard SQL problems on LeetCode and StartCode.
• Resources:
  • CodeHelp video on DBMS fundamentals
  • DataWithBar’s SQL full course (visual explanations)
  • Ankit Bunal’s SQL interview questions playlist
  • LeetCode and StartCode for problem practice

3. Linux

• Essential because most data engineering tools run on Linux.
• Skills: file system navigation, permissions, resource monitoring (top, edtop), scripting, cron jobs, parsing files, using curl.
• Resource: Corey Schafer’s Linux/Mac tutorial playlist.

4. Processing (Spark & Kafka)

• Spark is core to big data processing; learn architecture (master/workers), memory management, jobs/stages/tasks, optimization (partitioning, bucketing, caching, broadcast joins, AQE, dynamic partition pruning).
• Kafka is essential for streaming data ingestion and processing (e.g., user activity tracking).
• Resources:
  • Spark: The Definitive Guide (book)
  • High Performance Spark (book)
  • Speaker’s own Apache Spark YouTube playlist
  • Udemy course: Taming Big Data with Apache Spark
  • Kafka: Kafka: The Definitive Guide (book), Apache Kafka series by Stephane Maarek (course)

5. Data Modeling & Data Warehousing

• Model data to answer business questions (e.g., Uber’s trips, payments, reviews).
• Start with Kimball’s Data Warehousing Toolkit (first 3 chapters).
• Understand star schema, snowflake schema, facts and dimensions, slowly changing dimensions.
• Don’t worry initially about Kimball vs Inmon vs Data Vault; focus on fundamentals.
• Supplement difficult concepts with online resources or ChatGPT explanations.

6. Orchestration

• Manage and schedule pipelines, handle dependencies, retries, alerts.
• Airflow is the most popular tool; alternatives include Prefect, Mage, Daxter.
• Resource: Udemy course Apache Airflow: The Hands-On Guide by Mark Lamberti.
• Consider Airflow certifications (paid).

7. Cloud Platforms

• Learn cloud basics: VMs (EC2), IAM, security groups, logging (CloudWatch).
• Pick any major cloud provider (AWS, Azure, GCP); recommended: Azure for its data engineering services.
• Certifications (AWS Solutions Architect, Azure Data Engineer) are helpful but mastery comes on the job.
• Hands-on practice by creating buckets, clusters, etc.

8. Git

• Version control is essential for collaboration, code review, CI/CD.
• Maintain a strong Git portfolio with projects, README files, architecture diagrams.
• Resources:
  • Complete Git and GitHub Tutorial by Kunal
  • 11-hour deep dive course by Bogdan

9. CI/CD

• Automate testing and validation on code merges to prevent bugs.
• Tools: Jenkins, CircleCI, TravisCI, GitHub Actions.
• Practice integrating CI/CD pipelines with your projects.
• Write unit tests to simulate merges and validation.

10. DevOps (Advanced)

• Deployment and maintenance of pipelines.
• Infrastructure as Code (IaC) with Terraform and CloudFormation.
• Containerization with Docker.
• Collaborate with infrastructure teams or manage infra yourself.
• Resources:
  • Udemy: HashiCorp Certified Terraform Associate by Zeal Vora
  • Stephen Grider’s Docker course (includes project)

11. Projects (Most Important)

• Build meaningful projects applying all learned skills.
• Use free cloud credits (AWS, Azure, GCP, Databricks).
• Prefer understanding architecture and plugging in concepts rather than blindly following tutorials.
• Example projects and resources:
  • DataTalksClub Data Engineering Zoomcamp GitHub repo
  • Projects involving API data extraction, ETL, data warehousing, dashboards
  • Real-time streaming pipelines with Airflow, dbt, BigQuery, Terraform
  • Goodreads data pipeline with EMR, S3, Redshift, Airflow
  • YouTube playlists by Dil Parmar and CodeWithYou featuring end-to-end data engineering projects
