Скачать или смотреть Software Architecture in Golang: Circuit Breaker Cloud Design Pattern for Reliability

Welcome to another Software Architecture in Go video, in today's episode we are covering a Cloud Design Pattern for improving Reliability called "Circuit Breaker".

What is "Circuit Breaker", this pattern handles errors that could take some amount of time to fix when connecting to a remote service, like a microservice. The idea is to detect those errors, determine how to react to them and have a process to retry the requests that previously failed.

Behind the scenes this pattern defines three states: "closed", "half-open" and "open", those are used to determine the steps to execute when failures stop and/or failures start.

For this specific example we are using: github.com/mercari/go-circuitbreaker, but there are few other implementations like:

https://github.com/sony/gobreaker
https://github.com/cep21/circuit
https://github.com/afex/hystrix-go
https://github.com/rubyist/circuitbre...

In the end all of them follow the same pattern, I like mercari's because it uses context.Context as a way to also determine failures.
