Types ¶
type AutoScaler ¶
type AutoScaler interface {
Estimator
// Acquire X ResourceUnit of resource
Acquire(ResourceUnit) error
// Release X ResourceUnit of resource
Release(ResourceUnit)
// GetCurrent ResourceUnit of resource
GetCurrent() ResourceUnit
// Start starts the autoscaler go routine that scales the ResourceUnit according to Estimator
Start()
// Stop stops the autoscaler if started or do nothing if not yet started
Stop()
}
AutoScaler collects data and estimate usage
type Estimator ¶
type Estimator interface {
CollectUsage(data interface{}) error
Estimate() (Usages, error)
Reset()
}
Estimator collects data and estimate usage
type MilliUsage ¶
type MilliUsage uint64
MilliUsage is the custom defined usage of ResourceUnit times 1000
func (MilliUsage) Value ¶
func (u MilliUsage) Value() float64
Value helper method for type conversion
type Recommender ¶
type Recommender interface {
Recommend(currentResource ResourceUnit, currentUsages Usages) ResourceUnit
}
Recommender a recommendation generator for ResourceUnit
func NewLinearRecommender ¶
func NewLinearRecommender(lower, upper ResourceUnit, targetUsages Usages) Recommender
NewLinearRecommender create a linear Recommender
type ResourceUnit ¶
type ResourceUnit uint
ResourceUnit is the unit of scalable resources
func (ResourceUnit) Value ¶
func (r ResourceUnit) Value() float64
Value helper method for type conversion
type UsageType ¶
type UsageType string
UsageType type of usage
const ( // PollerUtilizationRate is a scale from 0 to 1 to indicate poller usages PollerUtilizationRate UsageType = "pollerUtilizationRate" )
type Usages ¶
type Usages map[UsageType]MilliUsage
Usages are different measurements used by a Recommender to provide a recommended ResourceUnit
