should the elapsedTime subtraction come after this reset to the MIN_CONNECTION timeout? For example, if we spent 1s on the status check and the MIN_CONNECTION timeout is 3s, we only have to wait 2s

I was thinking about this scenario but I guess it makes sense to avoid checking node status too often. So MIN_CONNECTION is applied to delayMillis.

I think these methods can be simplified if you add a getter for cacheItem.item:
public V getItem() {
return isExpired() ? null : item;
}
