Types ¶

	Add(key string, p []byte, opts ...Option)
	FetchAt(key string, offset int64, p []byte, opts ...Option) (n int, err error)
}

func NewDirectoryCache ¶

func NewMemoryCache ¶

func NewMemoryCache() BlobCache

type DirectoryCacheConfig ¶

type DirectoryCacheConfig struct {
	MaxLRUCacheEntry int
	MaxCacheFds      int
	SyncAdd          bool
}

type Option ¶

type Option func(o *cacheOpt) *cacheOpt

func Direct ¶

func Direct() Option

When Direct option is specified for FetchAt and Add methods, these operation won't use on-memory caches. When you know that the targeting value won't be used immediately, you can prevent the limited space of on-memory caches from being polluted by these unimportant values.
