Types

type Cache

type Cache interface {
	Query(app, env, key string) (*concept.Element, bool)
	Set(app, env, key string, elem *concept.Element)
}

func NewCache

func NewCache(size uint) Cache

NewCache construct a cache instance to help app manages caches. FIXED(@yeqown): how to clear caches? or cache items will be released at time. Solution: limit cache size with cache replacing algorithm so that no need to worry about OOM.

DONE(@yeqown): using LRU-2 cache replacing algorithm to limit cache.

type InstancePool

type InstancePool interface {
	Register(insId string, app, env string, keys []string) <-chan *concept.Element

	Unregister(insId string)

	Notify(insId string, element *concept.Element)

	ListWatchingInstances(app, env, key string) set.StringSet
}

InstancePool is a pool provide open API ability to Register / Unregister / Notify instances.
