Interface Summary

Interface	Description
CompactionLifeCycleTracker	Used to track compaction execution.
CompactionRequest	Coprocessors use this interface to get details about compaction.
CompactionRequester	Request a compaction.
Compactor.CellSinkFactory<S>
Compactor.InternalScannerFactory
StripeCompactionPolicy.StripeInformationProvider	The information about stripes that the policy needs to do its stuff

Class Summary

Class	Description
AbstractMultiOutputCompactor<T extends AbstractMultiFileWriter>	Base class for implementing a Compactor which will generate multiple output files after compaction.
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.
CompactionRequestImpl	This class holds all logical details necessary to run a compaction.
CompactionWindow	Base class for compaction window implementation.
CompactionWindowFactory	For creating compaction window.
Compactor<T extends CellSink>	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
DateTieredCompactionPolicy	HBASE-15181 This is a simple implementation of date-based tiered compaction similar to Cassandra's for the following benefits: Improve date-range-based scan by structuring store files in date-based tiered layout. Reduce compaction overhead. Improve TTL efficiency. Perfect fit for the use cases that: has mostly date-based data write and scan and a focus on the most recent data. Out-of-order writes are handled gracefully.
DateTieredCompactionRequest
DateTieredCompactor	This compactor will generate StoreFile for different time ranges.
DefaultCompactor	Compact passed set of files.
ExploringCompactionPolicy	Class to pick which files if any to compact together.
ExponentialCompactionWindowFactory	Exponential compaction window implementation.
FIFOCompactionPolicy	FIFO compaction policy selects only files which have all cells expired.
OffPeakHours
RatioBasedCompactionPolicy	The default algorithm for selecting files for compaction.
SortedCompactionPolicy	An abstract compaction policy that select files on seq id order.
StripeCompactionPolicy	Stripe store implementation of compaction policy.
StripeCompactionPolicy.StripeCompactionRequest	Stripe compaction request wrapper.
StripeCompactor	This is the placeholder for stripe compactor.
