Uses of CompactionPolicy in org.apache.hadoop.hbase.regionserver.compactions

Subclasses of CompactionPolicy in org.apache.hadoop.hbase.regionserver.compactions

Modifier and Type	Class	Description
class	CustomDateTieredCompactionPolicy	Custom implementation of DateTieredCompactionPolicy that calculates compaction boundaries based on the hbase.hstore.compaction.date.tiered.custom.age.limit.millis configuration property and the TIERING_CELL_MIN/TIERING_CELL_MAX stored on metadata of each store file.
class	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.
class	ExploringCompactionPolicy	Class to pick which files if any to compact together.
class	FIFOCompactionPolicy	FIFO compaction policy selects only files which have all cells expired.
class	RatioBasedCompactionPolicy	The default algorithm for selecting files for compaction.
class	SortedCompactionPolicy	An abstract compaction policy that select files on seq id order.
class	StripeCompactionPolicy	Stripe store implementation of compaction policy.
