Class	Description
ConfigurableScanServerHostSelector	Extension of the ConfigurableScanServerSelector that can be used when there are multiple ScanServers running on the same host and for some reason, like using a shared off-heap cache, sending scans for the same tablet to the same host may provide a better experience.
ConfigurableScanServerSelector	The default Accumulo selector for scan servers.
ConfigurableScanServerSelector.Profile
HintScanPrioritizer	When configured for a scan executor, this prioritizer allows scanners to set priorities as integers.
IdleRatioScanPrioritizer	Prioritize scans based on the ratio of runTime/idleTime.
ScanDispatch	Encapsulates information about how a scan should be executed.
ScanDispatch.Builder
ScanDispatch.CacheUsage	Communicates how a scan should use cache.
ScanDispatcher	A per table scan dispatcher that decides which executor should be used to process a scan.
ScanDispatcher.DispatchParameters	The method parameters for ScanDispatcher.dispatch(DispatchParameters).
ScanDispatcher.DispatchParmaters	Deprecated. since 2.1.0 replaced by ScanDispatcher.DispatchParameters and ScanDispatcher.dispatch(DispatchParameters)
ScanDispatcher.InitParameters	The method parameters for ScanDispatcher.init(InitParameters).
ScanExecutor	Interface for obtaining information about a scan executor
ScanExecutor.Config
ScanInfo	Provides information about an active Accumulo scan against a tablet.
ScanInfo.Type
ScanPrioritizer	A factory for creating comparators used for prioritizing scans.
ScanPrioritizer.CreateParameters	The method parameters for ScanPrioritizer.createComparator(CreateParameters).
ScanServerAttempt	This object is used to communicate what previous actions were attempted, when they were attempted, and the result of those attempts
ScanServerAttempt.Result
ScanServerInfo	Information about a scan server.
ScanServerSelections	Returned by ScanServerSelector.selectServers(ScanServerSelector.SelectorParameters) to specify what scan servers to use and how to use them.
ScanServerSelector	A client side plugin that determines what scan servers to use for eventually consistent scans.
ScanServerSelector.InitParameters	This interface exists so that is easier to evolve what is passed to ScanServerSelector.init(InitParameters) without having to make breaking changes.
ScanServerSelector.SelectorParameters	This interface exists so that is easier to evolve what is passed to ScanServerSelector.selectServers(SelectorParameters) without having to make breaking changes.
SimpleScanDispatcher	If no options are given, then this will default to an executor named default and ScanDispatch.CacheUsage.TABLE for index and data cache.
