A particularly valuable section for developers distributing the PDF among teams is the deep dive into connection pooling. Mihalcea explains the physics of database connections—how they are established, why they are expensive, and how tools like HikariCP can be tuned. He moves beyond simple configuration to explain the relationship between connection pool size, database thread counts, and response time percentiles. This technical depth transforms the book from a coding manual into a system architecture guide.
6 — Query discipline and SQL mastery
The "High-Performance" aspect of the title is earned in these chapters, which cover:
