BrokerManagedAsyncExecutorProvider	BrokerManagedAsyncExecutorProvider provides a bounded thread pool.
BrokerRequestHandler
BrokerRequestHandlerDelegate	BrokerRequestHandlerDelegate delegates the inbound broker request to one of the enabled BrokerRequestHandler based on the requested handle type.

HitCounter	This hit counter is for counting the number of hits within a range of time.
HttpRequesterIdentity	Identity container for HTTP requests with (optional) authorization headers
HybridSelector	The HybridSelector is an AdaptiveServerSelector implementation that picks the best server based on the following parameters: 1.
InstanceResource	This resource API can be used to retrieve instance level information like instance tags.
InstanceSelector	The instance selector selects server instances to serve the query based on the selected segments.
InstanceSelector.SelectionResult
InstanceSelectorFactory
Interval	The Interval class represents an one-dimensional closed interval which contains both ends.
IntervalTree<VALUE>	The IntervalTree class represents read-only balanced binary interval tree map (from intervals to values)
LatencySelector	The LatencySelector is an AdaptiveServerSelector implementation that picks the best server based on the exponential weighted moving average (EMA) of query latencies seen by the server.
MaxHitRateTracker	A stateful version of hit counter.
MultiPartitionColumnsSegmentPruner	The MultiPartitionColumnsSegmentPruner prunes segments based on their partition metadata stored in ZK.
MultiStageBrokerRequestHandler
MultiStageReplicaGroupSelector	Instance selector for multi-stage queries which can ensure that Colocated Tables always leverage Colocated Join whenever possible.
NewSegmentState	Contains the push time and candidate instances for a new segment.
NoOpFailureDetector
NumInFlightReqSelector	The NumInFlightReqSelector is an AdaptiveServerSelector implementation that picks the best server based on the number of in-flight queries being processed by the server.

QueryQuotaEntity
QueryQuotaManager
ReplicaGroupInstanceSelector	Instance selector for replica-group routing strategy.
RequesterIdentity
SegmentInstanceCandidate	Represents an instance candidate for a segment.
SegmentLineageBasedSegmentPreSelector	Segment lineage based segment pre-selector This pre-selector reads the segment lineage metadata and filters out either merged segments or original segments to make sure that the final segments contain no duplicate data.
SegmentPartitionInfo
SegmentPartitionMetadataManager	The PartitionDataManager manages partitions of a table.
SegmentPartitionUtils
SegmentPreSelector	The segment pre-selector filters the unnecessary online segments for the query.
SegmentPreSelectorFactory
SegmentPruner	The segment pruner prunes the selected segments based on the query.
SegmentPrunerFactory
SegmentSelector	The segment selector selects the segments for the query.
SegmentSelectorFactory
SegmentStates	The SegmentStates contains the candidate instances for each segment, and the unavailable segments for routing purpose.
SegmentZkMetadataFetcher	SegmentZkMetadataFetcher is used to cache ZNRecord stored in ZkHelixPropertyStore for segments.
SegmentZkMetadataFetchListener	Interface to register with SegmentZkMetadataFetcher.
SingleConnectionBrokerRequestHandler	The SingleConnectionBrokerRequestHandler class is a thread-safe broker request handler using a single connection per server to route the queries.
SinglePartitionColumnSegmentPruner	The SinglePartitionColumnSegmentPruner prunes segments based on their partition metadata stored in ZK.
StrictReplicaGroupInstanceSelector	Instance selector for strict replica-group routing strategy.
TimeBoundaryManager	The TimeBoundaryManager class manages the time boundary information for a table.
TimeSegmentPruner	The TimeSegmentPruner prunes segments based on their time column start & end time metadata stored in ZK.
