non_idempotent 在Nginx文档中可以看到proxy_next_upstream有一个选项non_idempotent: normally, requests with a non-idempotent method (POST, LOCK, PATCH) are not passed to the next server if a request has been sent to an upstream server (1.9.13); enabling this option explicitly allows retrying suc...
加上non_idempotent选项后,即使是非幂等请求类型(例如POST请求),发生错误后也会重试。 如果想让POST请求也会失败重试,需要配置non_idempotent: upstreamnginxretry{server127.0.0.1:9030max_fails=0;server127.0.0.1:9031max_fails=0;}server{listen9039;location/{proxy_passhttp://nginxretry;proxy_next_upstreamerror...

【摘要】 Nginx通过反向代理做负载均衡时,如果被代理的其中一个服务发生错误或者超时的时候,通常希望Nginx自动重试其他的服务,从而实现服务的高可用性。实际上Nginx本身默认会有错误重试机制,并且可以通过proxy_next_upstream来自定义配置。 如果不了解HTTP协议以及Nginx的机制,就可能在使用过程中遇到各种各样的坑。例......

We characterize interlacity of a weakly idempotent semilattice operation, using the concept of hyperidentity and prove that a weakly ...

This problem is reminiscent of the problem of handling non-undoable and non-idempotent operations in Section 4.4, where we wanted to process the output of a transaction (e.g., print a check) exactly once. In this case, we want to run T in the business process exactly once. It is ...
