Topics

Rails Connection Pools + PGBouncer

Rails DB Connections use the built in Rails Connection Pool. When used in combination with PGBouncer this allows for handling a much larger number of DB connections, but also leads to some unforeseen issues.

Sharing learnings about PGBouncer (What is it? Why use it?) and some important findings about managing the interaction between the Rails connection pool and a third party connection pool like PGBouncer.

Embracing Clarity and Flexibility with dry-rb

Abstract

dry-rb is a powerful set of Ruby libraries designed to promote code clarity, immutability, and maintainability—without compromising on flexibility. In this talk, I’ll introduce three core components of the dry-rb ecosystem: dry-struct, dry-validation, and dry-transaction. Together, they enable a clean, explicit approach to data modeling, validation, and business logic orchestration.

We'll explore:

  • How to use dry-struct for typed value objects and safer data handling
  • Validating input and domain data with dry-validation
  • Structuring business logic into composable steps with dry-transaction

I’ll walk through practical examples from real-world Ruby applications and demonstrate how these tools can replace tangled service classes and model callbacks with something more explicit, testable, and intention-revealing.

Target Audience

Rubyists of all levels who are curious about alternatives to Rails conventions or interested in writing more maintainable, modular business logic.
