Data Engineering

A book-shaped table of contents for data engineering: foundations and lifecycle, data modeling, storage systems, ingestion and CDC, distributed processing (Spark/Flink), SQL mastery, workflow orchestration, data quality, platform and cloud architecture, pipeline observability, security and governance, performance engineering, system design, and MAANG interview preparation through capstone builds — cross-linking the existing observability book instead of duplicating it.

2 — Cost Optimization

Cost optimization for data platforms — storage and compute cost drivers, compression, autoscaling, and spot instance strategies.

3 — Capacity Planning

Capacity planning for data systems — throughput estimation, scaling strategy, benchmarking, and load testing.

1 — What is Data Engineering?

How data engineering evolved into its own discipline, how the role differs from analytics engineering and data science, and the foundational distinctions (batch vs. streaming, OLTP vs. OLAP) that shape the rest of this book.
