|
| 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.
|
| CompactionRequest |
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 Compactor.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.
