Package org.elasticsearch.cluster.routing

Interface Summary

Interface	Description
HashFunction	Simple hash function interface used for shard routing.
ShardIterator	Allows to iterate over a set of shard instances (routing) within a shard id group.
ShardsIterator	Allows to iterate over unrelated shards.

Class Summary

Class	Description
AllocationId	Uniquely identifies an allocation.
DjbHashFunction	This class implements the efficient hash function developed by Daniel J.
GroupShardsIterator	This class implements a compilation of ShardIterators.
IndexRoutingTable	The IndexRoutingTable represents routing information for a single index.
IndexRoutingTable.Builder
IndexShardRoutingTable	IndexShardRoutingTable encapsulates all instances of a single shard.
IndexShardRoutingTable.Builder
Murmur3HashFunction	Hash function based on the Murmur3 algorithm, which is the default as of Elasticsearch 2.0.
OperationRouting
PlainShardIterator	The PlainShardIterator is a ShardsIterator which iterates all shards or a given shard id
PlainShardsIterator	A simple ShardsIterator that iterates a list or sub-list of shard routings.
RestoreSource	Represents snapshot and index from which a recovering index should be restored
RotationShardShuffler	Basic ShardShuffler implementation that uses an AtomicInteger to generate seeds and uses a rotation to permute shards.
RoutingNode	A RoutingNode represents a cluster node associated with a single DiscoveryNode including all shards that are hosted on that nodes.
RoutingNodes	RoutingNodes represents a copy the routing information contained in the cluster state.
RoutingNodes.UnassignedShards
RoutingService	A RoutingService listens to clusters state.
RoutingTable	Represents a global cluster-wide routing table for all indices including the version of the current routing state.
RoutingTable.Builder
RoutingTableValidation	Encapsulates the result of a routing table validation and provides access to validation failures.
ShardRouting	ShardRouting immutably encapsulates information about shard routings like id, state, version, etc.
ShardShuffler	A shuffler for shards whose primary goal is to balance load.
SimpleHashFunction	This class implements a simple hash function based on Java Build-In Object.hashCode()
UnassignedInfo	Holds additional information as to why the shard is in unassigned state.

Enum Summary

Enum	Description
Preference	Routing Preference Type
ShardRoutingState	Represents the current state of a ShardRouting as defined by the cluster.
UnassignedInfo.Reason	Reason why the shard is in unassigned state.

Exception Summary

Exception	Description
IllegalShardRoutingStateException	This exception defines illegal states of shard routing
RoutingException	A base Exceptions for all exceptions thrown by routing related operations.
RoutingValidationException	This class defines RoutingExceptions related to the validation of routing
