Class Summary

Class	Description
ArrayUtils	Operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]).
BitCaskDiskMap<T extends Serializable,R extends Serializable>	This class provides a disk spillable only map implementation.
BitCaskDiskMap.FileEntry	The file metadata that should be spilled to disk.
BitCaskDiskMap.ValueMetadata	The value relevant metadata.
CloseableMappingIterator<I,O>	MappingIterator requiring to be closed after iteration (to cleanup resources)
DiskMap<T extends Serializable,R extends Serializable>	This interface provides the map interface for storing records in disk after they spill over from memory.
ExternalSpillableMap<T extends Serializable,R extends Serializable>	An external map that spills content to disk when there is insufficient space for it to grow.
FlatLists	Space-efficient, comparable, immutable lists, copied from calcite core.
FlatteningIterator<T,I extends Iterator<T>>	Iterator flattening source Iterator holding other Iterators
ImmutablePair<L,R>	(NOTE: Adapted from Apache commons-lang3)
ImmutableTriple<L,M,R>	(NOTE: Adapted from Apache commons-lang3)
LazyFileIterable<T,R>	Iterable to lazily fetch values spilled to disk.
MappingIterator<I,O>	Iterator mapping elements of the provided source Iterator from I to O
Pair<L,R>	(NOTE: Adapted from Apache commons-lang3)
RocksDBBasedMap<K extends Serializable,R extends Serializable>	A map's implementation based on RocksDB.
RocksDBDAO	Data access objects for storing and retrieving objects in Rocks DB.
RocksDbDiskMap<T extends Serializable,R extends Serializable>	This class provides a disk spillable only map implementation.
Triple<L,M,R>	(NOTE: Adapted from Apache commons-lang3)
Tuple3<T0,T1,T2>	A tuple with 3 fields.
