hystix sentinel token tpslimit
# hystrix
Test 1:3 个请求全 success
- Test 2:15 个并发请求(并发上限 10,超出的会失败)
- Test 3:并发后再发 5 个,若熔断触发会看到 circuit open
- 触发熔断后等 5 秒(SleepWindow)再跑一次 client,能看到恢复

# sentinel
client 依次跑三个场景,每个打印 success: X fail: Y
- Greet 并发 150 → 被并发隔离(阈值 100)挡掉一部分,fail > 0
- GreetWithQPSLimit → server 端 QPS 限 100,有 block
- GreetWithChanceOfError → 故意发 error 触发熔断,随后打印状态迁移:Closed → Open →(等 2s)→
Half-Open → Closed
- 若出现 wait circuit breaker ... timeout 警告,

# token
server 用 token dubbo-go 注册,consumer 从注册中心自动拿到 token 并带上。成功则 client 打印 Greet
response: hello world,

/>
# tpslimit
client 发 60 个请求(间隔 200ms)。策略是随机 50% 拒绝 + 速率 5/秒,所以会交替看到:
- 成功:response: hello world
- 被拒:error: the request is rejected and doesn't have any default value
- server 端会打 Random IsAllowable! 和被拒时的自定义 handler 日志
- 最后 client 打印 successCount=..., failCount=...,两者都应 > 0
