LongAdderRateGauge (venice API)

java.lang.Object
- io.tehuti.metrics.stats.Gauge
- - com.linkedin.venice.stats.LongAdderRateGauge

All Implemented Interfaces:

io.tehuti.metrics.Measurable, io.tehuti.metrics.MeasurableStat, io.tehuti.metrics.Stat
```
public class LongAdderRateGauge
extends io.tehuti.metrics.stats.Gauge
```
This metric class is to optimize for high write throughput, low read throughput measurement use case instead of real-time measurement. The smallest measurement interval is 30 seconds.
