smartcache

The smartcache realizes smart in memory cache generation to minimize process blocks by using soft expire limit

Synopsis

var (
    expire     = 5*time.Minute
    softExpire = 1*time.Minute
)
ca := smartcache.New(expire, softExpire, func(ctx context.Context) (interface{}, error) {
    val, err := genCache(ctx)
    return val, err
})

Description

In in-memory cache generation, there are problems, for example, thundering herd problems, blocking processing when regenerating or etc., but smartcache avoids them by setting a soft expire limit.
