32: Circuit Breaker and Elixir Patterns with Allan MacGregor

We talk with Allan MacGregor about implementing the Circuit Breaker pattern in Elixir and compare that to just using a job library. We get into a fun discussion about design patterns in Elixir and designing for failure. Allan is creating a project called Site Guardian using the PETAL stack and shares his experiences with it and much more!
