熔断的概念:
[TencentCloudSDKException] code:FailedOperation.ServiceIsolate message:service is stopped due to arrears, please recharge your account in Tencent Cloud requestId:d3dce814-e22b-4d52-8d7b-805cbc8fc213

[TencentCloudSDKException] code:FailedOperation.ServiceIsolate message:service is stopped due to arrears, please recharge your account in Tencent Cloud requestId:a270745c-f4f8-4c69-9df3-4a24223cc444
降级概念:
熔断降级逻辑:A服务器调用B服务器,失败次数达到一定阈值后,A服务的断路器打开,就不再请求B服务,而是直接执行本地的fallback方法;这种方式叫熔断降级
超时降级:
同样是A服务调用B服务,B服务响应超过了A服务的设定阈值后,就会执行降级逻辑;
限流降级:
还是A服务调用B服务,服务A的连接已超过自身能承载的最大连接数,比如A能承载的连接数为5,但是目前的并发有6个请求同时进行,前5请求能正常请求,最后一个会直接拒绝,执行fallback降级逻辑;
熔断和降级的关系:
