Uses of AllocationDecider in org.elasticsearch.cluster.routing.allocation.decider

Subclasses of AllocationDecider in org.elasticsearch.cluster.routing.allocation.decider

Modifier and Type	Class	Description
class	AllocationDeciders	A composite AllocationDecider combining the "decision" of multiple AllocationDecider implementations into a single allocation decision.
class	AwarenessAllocationDecider	This AllocationDecider controls shard allocation based on awareness key-value pairs defined in the node configuration.
class	ClusterRebalanceAllocationDecider	This AllocationDecider controls re-balancing operations based on the cluster wide active shard state.
class	ConcurrentRebalanceAllocationDecider	Similar to the ClusterRebalanceAllocationDecider this AllocationDecider controls the number of currently in-progress re-balance (relocation) operations and restricts node allocations if the configured threshold is reached.
class	DiskThresholdDecider	The DiskThresholdDecider checks that the node a shard is potentially being allocated to has enough disk space.
class	EnableAllocationDecider	This allocation decider allows shard allocations / rebalancing via the cluster wide settings EnableAllocationDecider.CLUSTER_ROUTING_ALLOCATION_ENABLE_SETTING / EnableAllocationDecider.CLUSTER_ROUTING_REBALANCE_ENABLE_SETTING and the per index setting EnableAllocationDecider.INDEX_ROUTING_ALLOCATION_ENABLE_SETTING / EnableAllocationDecider.INDEX_ROUTING_REBALANCE_ENABLE_SETTING.
class	FilterAllocationDecider	This AllocationDecider control shard allocation by include and exclude filters via dynamic cluster and index routing settings.
class	MaxRetryAllocationDecider	An allocation decider that prevents shards from being allocated on any node if the shards allocation has been retried N times without success.
class	NodeVersionAllocationDecider	An allocation decider that prevents relocation or allocation from nodes that might not be version compatible.
class	RebalanceOnlyWhenActiveAllocationDecider	Only allow rebalancing when all shards are active within the shard replication group.
class	ReplicaAfterPrimaryActiveAllocationDecider	An allocation strategy that only allows for a replica to be allocated when the primary is active.
class	ResizeAllocationDecider	An allocation decider that ensures we allocate the shards of a target index for resize operations next to the source primaries
class	RestoreInProgressAllocationDecider	This AllocationDecider prevents shards that have failed to be restored from a snapshot to be allocated.
class	SameShardAllocationDecider	An allocation decider that prevents multiple instances of the same shard to be allocated on the same node.
class	ShardsLimitAllocationDecider	This AllocationDecider limits the number of shards per node on a per index or node-wide basis.
class	SnapshotInProgressAllocationDecider	This AllocationDecider prevents shards that are currently been snapshotted to be moved to other nodes.
class	ThrottlingAllocationDecider	ThrottlingAllocationDecider controls the recovery process per node in the cluster.
