          Description

Interface Summary
DistributionManager A DistributionManager coordinates the distribution of partitions for a partitioned service.
KeyAssociator A KeyAssociator provides key associations on behalf of a set of keys.
KeyPartitioningStrategy A KeyPartitioningStrategy is a pluggable strategy for assigning keys to specific partitions.
KeyPartitioningStrategy.PartitionAwareKey PartitionAwareKey is a well-known interface that should be respected by KeyPartitioningStrategy implementations.
PartitionAssignmentStrategy A PartitionAssignmentStrategy is a pluggable strategy used by a PartitionedService to manage partition distribution.
PartitionAwareBackingMap In a partitioned configuration, backing maps that implement the PartitionAwareBackingMap interface are able to react to the partition life-cycle (a partition showing up on a node, or moving away from a node) and manage data more efficiently as a result.
PartitionListener The listener interface for receiving PartitionEvents.
SimpleAssignmentStrategy.LoadCalculator LoadCalculator is used to calculate the scalar load (expressed as an integer) of a partition (or set of partitions).

 

Class Summary
BroadKeyPartitioningStrategy The BroadKeyPartitioningStrategy is a strategy that could be used in cases when the standard key association-based strategy produces very uneven partition distribution - some partitions having significantly larger amount of data than others.
DefaultKeyAssociator A DefaultKeyAssociator provides key associations on behalf of keys that implement the KeyAssociation interface.
DefaultKeyPartitioningStrategy DefaultKeyPartitioningStrategy provides a simple strategy for assigning keys to partitions which is based on the hash code of keys in internal (serialized to Binary) form.
ObservableSplittingBackingCache The ObservableSplittingBackingCache is an implementation of the ConfigurableCacheMap interface that works as an observable backing map in a partitioned system.
ObservableSplittingBackingMap An observable, cache-aware PartitionAwareBackingMap implementation.
Ownership Ownership is a light-weight data structure that contains a partition ownership information.
PartitionedIterator An Iterator that iterates over keys in a partition-by-partition or member-by-member manner.
PartitionEvent The PartitionEvent carries information about an event related to one or more partitions.
PartitionSet PartitionSet is a light-weight data structure that represents a set of partitions that are used in parallel processing.
PartitionSplittingBackingMap In a partitioned configuration, the PartitionSplittingBackingMap is a "map multi-plexer" that enables multiple backing maps to be used in place of a single backing map.
PartitionSplittingBackingMap.MapArray The MapArray is a data structure that provides a mapping between partition IDs and backing maps.
ReadWriteSplittingBackingMap A PartitionAwareBackingMap extension to the ReadWriteBackingMap.
SimpleAssignmentStrategy SimpleAssignmentStrategy is a PartitionAssignmentStrategy that attempts to balance the partition distribution based on the number of primary and backup partitions owned.
SimpleAssignmentStrategy.BackupStrength BackupStrength represents a level of "strength" or "resiliency" between the primary and backup owners of a partition.
SimpleAssignmentStrategy.SimpleLoadCalculator SimpleLoadCalculator defines a "count-based" load (e.g. the load of each partition is defined to be 1).
SimplePartitionKey SimplePartitionKey is a trivial PartitionAwareKey implementation.
