Package org.apache.hadoop.hbase.regionserver.compactions

Interface Summary

Interface	Description
CompactionThroughputController	A utility that constrains the total throughput of one or more simultaneous flows (compactions) by sleeping when necessary.
Compactor.CellSink
StripeCompactionPolicy.StripeInformationProvider	The information about stripes that the policy needs to do its stuff

Class Summary

Class	Description
CompactionConfiguration	Compaction configuration for a particular instance of HStore.
CompactionContext	This class holds all "physical" details necessary to run a compaction, and abstracts away the details specific to a particular compaction.
CompactionPolicy	A compaction policy determines how to select files for compaction, how to compact them, and how to generate the compacted files.
CompactionProgress	This class holds information relevant for tracking the progress of a compaction.
CompactionRequest	This class holds all logical details necessary to run a compaction.
CompactionThroughputControllerFactory
Compactor	A compactor is a compaction algorithm associated a given policy.
Compactor.FileDetails	The sole reason this class exists is that java has no ref/out/pointer parameters.
CurrentHourProvider
DefaultCompactor	Compact passed set of files.
ExploringCompactionPolicy	Class to pick which files if any to compact together.
NoLimitCompactionThroughputController	A dummy CompactionThroughputController that does nothing.
OffPeakHours
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 tune 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]
RatioBasedCompactionPolicy	The default algorithm for selecting files for compaction.
StripeCompactionPolicy	Stripe store implementation of compaction policy.
StripeCompactionPolicy.StripeCompactionRequest	Stripe compaction request wrapper.
StripeCompactor	This is the placeholder for stripe compactor.
