Functions ¶

func ClearRules ¶

func ClearRules() error

ClearRules clears all the rules in isolation module.

func IsValid ¶

func IsValid(r *Rule) error

IsValidRule checks whether the given Rule is valid.

func LoadRules ¶

func LoadRules(rules []*Rule) (updated bool, err error)

LoadRules loads the given isolation rules to the rule manager, while all previous rules will be replaced.

Types ¶

type MetricType ¶

type MetricType int32

MetricType represents the target metric type.

const (
	// Concurrency represents concurrency count.
	Concurrency MetricType = iota
)

func (MetricType) String ¶

func (s MetricType) String() string

type Rule ¶

type Rule struct {
	// ID represents the unique ID of the rule (optional).
	ID         string     `json:"id,omitempty"`
	Resource   string     `json:"resource"`
	MetricType MetricType `json:"metricType"`
	Threshold  uint32     `json:"threshold"`
}

Rule describes the concurrency num control, that is similar to semaphore

func GetRules ¶

func GetRules() []Rule

GetRules returns all the rules based on copy. It doesn't take effect for isolation module if user changes the rule.

func GetRulesOfResource ¶

func GetRulesOfResource(res string) []Rule

GetRulesOfResource returns specific resource's rules based on copy. It doesn't take effect for isolation module if user changes the rule.

func (*Rule) ResourceName ¶

func (r *Rule) ResourceName() string

func (*Rule) String ¶

func (r *Rule) String() string

type Slot ¶

type Slot struct {
}

func (*Slot) Check ¶

func (s *Slot) Check(ctx *base.EntryContext) *base.TokenResult

func (*Slot) Name ¶

func (s *Slot) Name() string
