All Implemented Interfaces:

ai.platon.pulsar.common.collect.Loadable , ai.platon.pulsar.common.collect.queue.LoadingQueue , java.util.Queue , kotlin.collections.Collection , kotlin.collections.Iterable , kotlin.collections.MutableCollection , kotlin.collections.MutableIterable
```
public abstract class AbstractLoadingQueue
extends AbstractQueue<UrlAware> implements LoadingQueue<UrlAware>
                    
```
An url queue should be small since every url uses about 1s to fetch
