Functions

func NewConsecutiveBreaker

func NewConsecutiveBreaker() filters.Spec

NewConsecutiveBreaker creates a filter specification to instantiate consecutiveBreaker() filters.

These filters set a breaker for the current route that open if the backend failures for the route reach a value of N, where N is a mandatory argument of the filter:

consecutiveBreaker(15)

The filter accepts the following optional arguments: timeout (milliseconds or duration string), half-open-requests (integer), idle-ttl (milliseconds or duration string).

func NewDisableBreaker

func NewDisableBreaker() filters.Spec

NewDisableBreaker disables the circuit breaker for a route. It doesn't accept any arguments.

func NewRateBreaker

func NewRateBreaker() filters.Spec

NewRateBreaker creates a filter specification to instantiate rateBreaker() filters.

These filters set a breaker for the current route that open if the backend failures for the route reach a value of N within a window of the last M requests, where N and M are mandatory arguments of the filter:

rateBreaker(30, 300)

The filter accepts the following optional arguments: timeout (milliseconds or duration string), half-open-requests (integer), idle-ttl (milliseconds or duration string).
