Is it possible to optimize the processing efficiency of FastForward?

[happyandy2016]

// fastForward proceeds the current timestamp with duration, works as a time machine
func (db *RedisDB) fastForward(duration time.Duration) {
for _, key := range db.allKeys() {
if value, ok := db.ttl[key]; ok {
db.ttl[key] = value - duration
db.checkTTL(key)
}
}
}
The current function has to traverse all elements. Could we implement a time-sorted queue that only handles expired items to minimize unnecessary traversal?

Technically, sure. Or move the check to where the keys are used. I'm curious why you need this, do add so many keys? One of my main goals is to keep the code as simple as possible.
