CachedUIdWorker (Bigbird Framework 1.0.0-SNAPSHOT API)

java.lang.Object
- wang.bigbird.domain.framework.id.strategy.baidu.impl.DefaultUIdWorker
- - wang.bigbird.domain.framework.id.strategy.baidu.impl.CachedUIdWorker

所有已实现的接口:

UIdWorker
```
public class CachedUIdWorker
extends DefaultUIdWorker
```
Represents a cached implementation of UIdWorker extends from DefaultUIdWorker, based on a lock free RingBuffer

The spring properties you can specified as below:
boostPower: RingBuffer size boost for a power of 2, Sample: boostPower is 3, it means the buffer size will be (BitsAllocator#getMaxSequence() + 1) << boostPower, Default as
paddingFactor: Represents a percent value of (0 - 100). When the count of rest available UIDs reach the threshold, it will trigger padding buffer. Default asRingBuffer.DEFAULT_PADDING_PERCENT Sample: paddingFactor=20, bufferSize=1000 -> threshold=1000 * 20 /100, padding buffer will be triggered when tail-cursorscheduleInterval: Padding buffer in a schedule, specify padding buffer interval, Unit as second
rejectedPutBufferHandler: Policy for rejected put buffer. Default as discard put request, just do logging
rejectedTakeBufferHandler: Policy for rejected take buffer. Default as throwing up an exception
