High Performance PostgreSQL for Rails

Because modern Rails applications demand speed and reliability, this course explains how PostgreSQL works under the hood and, therefore, how you can extract maximum performance from it. Moreover, you will move beyond defaults and learn proven techniques that experienced engineers use in high-traffic environments. As a result, you will confidently handle growing datasets, increasing users, and complex queries without sacrificing stability.

What You Will Learn

First, the course explores PostgreSQL internals, including query planning, indexing strategies, and memory usage. Additionally, you will learn how ActiveRecord interacts with PostgreSQL, which helps you write more efficient Rails code. Furthermore, the course demonstrates how to analyze slow queries, interpret execution plans, and apply optimizations that deliver measurable improvements.

Next, you will master indexing techniques such as B-tree, GIN, and partial indexes. Consequently, your applications will respond faster even under heavy load. Meanwhile, you will also discover how to structure schemas, migrations, and associations so that performance remains predictable as your application evolves.

Performance Tuning for Real Applications

This course emphasizes real-world scenarios rather than theory alone. Therefore, you will work through examples involving background jobs, reporting queries, and API-heavy workloads. Moreover, you will learn how to configure PostgreSQL settings for Rails deployments, including connection pooling, caching, and concurrency management.

In addition, the course covers monitoring and benchmarking tools so you can measure improvements accurately. As a result, you will make data-driven decisions instead of relying on guesswork. However, the focus always remains on practical techniques that you can apply immediately.

Who This Course Is For

This course is ideal for Rails developers, backend engineers, and DevOps professionals who want faster applications and more reliable databases. Whether you maintain a growing startup or a mature enterprise system, you will benefit from clear explanations and actionable strategies. Ultimately, the skills you gain will help you deliver smoother user experiences and reduce infrastructure costs.
