Creating unique, chronological IDs in a multi-node environment. The "Hacking" Framework
Designing spatial indexing and location-based searches using R-trees.
Before diving into specific problems, the guide establishes the "building blocks" of modern architecture:
Detailed looks at web servers, API Gateways , load balancers, and CDNs.
Key concepts including data modeling, SQL vs. NoSQL trade-offs, sharding , replication, and the CAP theorem.
Map out the basic database tables and API endpoints.
The book is divided into two primary sections: theoretical fundamentals and practical interview scenarios.
Zoom in on specific bottlenecks, like caching strategies or database sharding.
