Class	Description
AbstractReindexingRule	Base implementation for reindexing rules that apply based on data age thresholds.
BaseCandidateSearchPolicy	Base implementation of CompactionCandidateSearchPolicy that can have a priorityDatasource.
CompactionCandidate	Non-empty list of segments of a datasource being considered for compaction.
CompactionCandidateSearchPolicy	Policy used by CompactSegments duty to pick segments for compaction.
CompactionMode	Represents the mode of compaction for segment intervals.
CompactionProgressResponse	Response of /compaction/progress API exposed by Coordinator and Overlord (when compaction supervisors are enabled).
CompactionRunSimulator	Deprecated. The simulator does not support the Overlord-based CompactionJobQueue or the new reindexing templates.
CompactionSegmentIterator	Iterator over compactible segments.
CompactionSimulateResult
CompactionSlotManager	Fetches running compaction tasks from the Overlord and tracks their compaction intervals and task slots.
CompactionSnapshotBuilder	Builds AutoCompactionSnapshot for multiple datasources using the identified CompactionCandidate list.
CompactionStatistics	Used to track statistics for segments in different states of compaction.
CompactionStatus	Represents the status of compaction for a given CompactionCandidate.
CompactionStatus.State
CompactionStatusResponse	Response of /compaction/status API exposed by Coordinator and Overlord (when compaction supervisors are enabled).
CompactionStatusTracker	Tracks status of recently submitted compaction tasks.
CompactionTaskStatus
ComposingReindexingRuleProvider	A meta-provider that composes multiple ReindexingRuleProviders with first-wins semantics.
DataSourceCompactibleSegmentIterator	Iterator over compactible segments of a datasource in order of specified priority.
Eligibility	Describes the eligibility of an interval for compaction.
FixedIntervalOrderPolicy	Implementation of CompactionCandidateSearchPolicy that specifies the datasources and intervals eligible for compaction and their order.
FixedIntervalOrderPolicy.Candidate	Specifies a datasource-interval eligible for compaction.
InlineReindexingRuleProvider	Rule provider that returns a static list of rules defined inline in the configuration.
InlineReindexingRuleProvider.Builder
IntervalPartitioningInfo	Associates a time interval with its partitioning information.
MostFragmentedIntervalFirstPolicy	Experimental CompactionCandidateSearchPolicy which prioritizes compaction of intervals with the largest number of small uncompacted segments.
NewestSegmentFirstPolicy	Implementation of CompactionCandidateSearchPolicy that prioritizes intervals which have the latest data.
PriorityBasedCompactionSegmentIterator	Implementation of CompactionSegmentIterator that returns candidate segments in order of their priority.
ReindexingDataSchemaRule	A ReindexingRule that specifies a data schema for reindexing tasks to configure.
ReindexingDeletionRule	A ReindexingRule that specifies patterns to match for removing rows during reindexing.
ReindexingIndexSpecRule	A ReindexingRule that specifies an IndexSpec for reindexing tasks to configure.
ReindexingPartitioningRule	A ReindexingRule that specifies partitioning configuration for reindexing tasks.
ReindexingRule	Defines a reindexing configuration that applies to data based on age thresholds.
ReindexingRule.AppliesToMode	Indicates how a rule applies to a given time interval based on the rule's period threshold.
ReindexingRuleProvider	Provides compaction rules for different aspects of reindexing configuration.
Table	A simple table POJO with any number of rows and specified column names.
