Distributed systems are inherently abstract. Concepts like sharding, replication, and consensus algorithms are difficult to grasp through text alone. Xu’s book is lauded for its extensive use of diagrams. The illustrations are clean, step-by-step visualizations that map abstract concepts to concrete architecture.
The book is laser-focused on interview preparation, not distributed systems theory. If you want to understand consensus algorithms or distributed transactions at a rigorous level, you‘ll need additional resources.
