Types

type Refresh 

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

Refresh is responsible for background refreshing of cache entries. It periodically samples random shards and randomly selects "cold" entries (from the end of each shard's InMemoryStorage list) to refreshItem if necessary. Communication: provider->consumer (MPSC).

func New 

func New(ctx context.Context, cfg config.Config, storage lru.Storage, upstream upstream.Upstream) *Refresh

New constructs a Refresh.

func (*Refresh) Run 

func (r *Refresh) Run()

Run starts the refresher background loop. It runs a logger (if debugging is enabled), spawns a provider for sampling shards, and continuously processes shard samples for candidate responses to refreshItem.

type Refresher 

type Refresher interface {
	Run()
}
