IdleRatioScanPrioritizer (Apache Accumulo Core 2.1.0 API)

java.lang.Object
- org.apache.accumulo.core.spi.scan.IdleRatioScanPrioritizer

All Implemented Interfaces:

ScanPrioritizer
```
public class IdleRatioScanPrioritizer
extends Object
implements ScanPrioritizer
```
Prioritize scans based on the ratio of runTime/idleTime. Scans with a lower ratio have a higher priority. When the ratio is equal, the scan with the oldest last run time has the highest priority. If neither have run, then the oldest gets priority.

Since:

2.0.0
