Functions

func NewBreaker

func NewBreaker(name string, opts ...Option) circuitbreaker.Breaker

Types

type Option

type Option func(breaker *breaker)

func WithErrorPercentThreshold

func WithErrorPercentThreshold(errorPercentThreshold int) Option

WithErrorPercentThreshold 错误百分比,默认值是50(当错误百分比超过这个限制时则进行熔断)。请求数量大于等于RequestVolumeThreshold并且错误率到达这个百分比后就会启动熔断

func WithMaxConcurrentRequests

func WithMaxConcurrentRequests(maxConcurrentRequests int) Option

WithMaxConcurrentRequests 最大并发量,默认值是10

func WithRequestVolumeThreshold

func WithRequestVolumeThreshold(requestVolumeThreshold int) Option

WithRequestVolumeThreshold 一个统计窗口10秒内请求数量。达到这个请求数量后才去判断是否要开启熔断,默认值是20(比如10秒内接到了11个请求只超过了1个)

func WithSleepWindow

func WithSleepWindow(sleepWindow int) Option

WithSleepWindow 熔断后多久去尝试服务是否可用,默认值是5000毫秒(熔断器打开到半打开的时间),milliseconds

func WithTimeout

func WithTimeout(timeout int) Option

WithTimeout 单次请求超时时间,默认时间是1000毫秒,milliseconds
