In our case, we will be using hystrix-go, it is a go port from Netflix’s hystrix library, how it works is essentially the same, even hystrix-go supports turbine along with its hystrix dashboard, but in my case, I rather use the datadog plugins, since we are using datadog to monitor our system. For more about how Hystrix works, refer to the Java Hystrix wiki Now let assume if a service is failed and our monitoring tools already spot it by sending alerts. I use http.Server with read/write timeouts, go-sql-driver/mysql and hystrix with context. hystrix-go aims to allow Go programmers to easily build applications with similar execution semantics of the Java-based Hystrix library.

Welcome, this is an example of simple REST API implementation with clean architecture written in Go with complete Dependency Injection along with Mocking example, following SOLID principles. Middleware. The purpose of monitoring is, whenever we spot problems, we could follow up them in a fast and proper way. Here are some excerpts When that system is healthy this will be the only thing which executes. 1、 Service avalanche Microservice architecture is to divide a single application into various small and connected services, and each service completes a single business function. An "open" circuit means it is disabled. // Flush purges all circuit and metric information from memory. Hystrix is a latency and fault tolerance library designed to isolate points of access to remote systems, services and 3rd party libraries, stop cascading failure and enable resilience in complex distributed systems where failure is inevitable. Meanwhile we investigate or fix the issues, there will be number of failure requests which potentially will cascade the error across multiple systems.
