Database Internals: A Deep Dive into How Distributed Data Systems Work is a technical systems book by Alex Petrov, published by O Reilly. It examines the mechanisms beneath database APIs and query languages: how records are laid out on disk, located efficiently, updated safely, replicated across machines, and kept coherent when machines fail. The book is organized around two connected concerns. Its storage-engine material explains the data structures and file-management decisions that shape local database performance and reliability. Its distributed-systems material addresses the additional coordination problems that emerge when data and computation span nodes. Rather than presenting a guide to administering one product, Petrov compares recurring implementation approaches and the trade-offs behind them. B-trees, log-structured merge trees, write-ahead logging, replication, consistency, transactions, failure detection, and consensus are treated as engineering building blocks. The intended reader is a backend or infrastructure engineer who already uses databases and wants a more concrete basis for evaluating performance behavior, operational risks, and architectural choices.
