PressureAwareFlushThroughputController (Apache HBase 1.4.11 API)

java.lang.Object
- org.apache.hadoop.conf.Configured
- - org.apache.hadoop.hbase.regionserver.throttle.PressureAwareThroughputController
  - - org.apache.hadoop.hbase.regionserver.throttle.PressureAwareFlushThroughputController

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, ThroughputController, Stoppable
```
@InterfaceAudience.LimitedPrivate(value="Configuration")
public class PressureAwareFlushThroughputController
extends PressureAwareThroughputController
```
A throughput controller which uses the follow schema to limit throughput
- If flush pressure is greater than or equal to 1.0, no limitation.
- In normal case, the max throughput is tuned between "hbase.hstore.flush.throughput.lower.bound" and "hbase.hstore.flush.throughput.upper.bound", using the formula "lower + (upper - lower) * flushPressure", where flushPressure is in range [0.0, 1.0)
