NodeSettingsService.Listener

public class EnableAllocationDecider
extends AllocationDecider
implements NodeSettingsService.Listener

This allocation decider allows shard allocations / rebalancing via the cluster wide settings CLUSTER_ROUTING_ALLOCATION_ENABLE / CLUSTER_ROUTING_REBALANCE_ENABLE and the per index setting INDEX_ROUTING_ALLOCATION_ENABLE / INDEX_ROUTING_REBALANCE_ENABLE. The per index settings overrides the cluster wide setting.

Allocation settings can have the following values (non-casesensitive):

• NONE - no shard allocation is allowed.
• NEW_PRIMARIES - only primary shards of new indices are allowed to be allocated
• PRIMARIES - only primary shards are allowed to be allocated
• ALL - all shards are allowed to be allocated

Rebalancing settings can have the following values (non-casesensitive):

• NONE - no shard rebalancing is allowed.
• REPLICAS - only replica shards are allowed to be balanced
• PRIMARIES - only primary shards are allowed to be balanced
• ALL - all shards are allowed to be balanced
