As applications grow, PostgreSQL tables inevitably scale from thousands of records to hundreds of millions or even billions. Performance degradation for large tables is rarely sudden; instead, it happens through a process of silent degradation over time.
Scaling Postgres’s high-concurrency handling capability can never rely on simply throwing more hardware at the problem. Each database connection incurs a hidden system tax, including Linux-level memory and CPU overhead, as well as Postgres-level MVCC (Multi-Version Concurrency Control) and locking constraints. To handle high-performance workloads, we need to stop guessing and start precisely tuning our systems by deeply understanding these underlying limitations.
This PostgreSQL tutorial helps you understand PostgreSQL quickly. You’ll master PostgreSQL very fast through many practical examples and apply the knowledge in developing applications using PostgreSQL.
