All Implemented Interfaces:

```
@InterfaceAudience.LimitedPrivate(value="Configuration")
public class PressureAwareCompactionThroughputController
extends PressureAwareThroughputController
```
A throughput controller which uses the follow schema to limit throughput
- If compaction pressure is greater than 1.0, no limitation.
- In off peak hours, use a fixed throughput limitation "hbase.hstore.compaction.throughput.offpeak"
- In normal hours, the max throughput is tuned between "hbase.hstore.compaction.throughput.lower.bound" and "hbase.hstore.compaction.throughput.higher.bound", using the formula "lower + (higer - lower) * compactionPressure", where compactionPressure is in range [0.0, 1.0]
