type ParentBasedSamplerConfig added in v0.29.0

type ParentBasedSamplerConfig struct {
	LocalParentSampled  bool `yaml:"local_parent_sampled"`
	RemoteParentSampled bool `yaml:"remote_parent_sampled"`
}

type RateLimiter added in v0.29.0

type RateLimiter struct {
	// contains filtered or unexported fields
}

func NewRateLimiter added in v0.29.0

func NewRateLimiter(creditsPerSecond, maxBalance float64) *RateLimiter

NewRateLimiter creates a new RateLimiter.

func (*RateLimiter) CheckCredit added in v0.29.0

func (rl *RateLimiter) CheckCredit(itemCost float64) bool

CheckCredit tries to reduce the current balance by itemCost provided that the current balance is not lest than itemCost.

func (*RateLimiter) Update added in v0.29.0

func (rl *RateLimiter) Update(creditsPerSecond, maxBalance float64)

Update changes the main parameters of the rate limiter in-place, while retaining the current accumulated balance (pro-rated to the new maxBalance value). Using this method instead of creating a new rate limiter helps to avoid thundering herd when sampling strategies are updated.
