public class ClusterRebalanceAllocationDecider
extends AllocationDecider

This AllocationDecider controls re-balancing operations based on the cluster wide active shard state. This decided can not be configured in real-time and should be pre-cluster start via cluster.routing.allocation.allow_rebalance. This setting respects the following values:

• indices_primaries_active - Re-balancing is allowed only once all primary shards on all indices are active.
• indices_all_active - Re-balancing is allowed only once all shards on all indices are active.
• always - Re-balancing is allowed once a shard replication group is active
