PressureAwareCompactionThroughputController
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]

PressureAwareFlushThroughputController
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)
