"transient" : {
"cluster.routing.allocation.node_concurrent_recoveries":4,
"cluster.routing.allocation.cluster_concurrent_rebalance":4,
"cluster.routing.allocation.node_initial_primaries_recoveries":5,
"indices.recovery.max_bytes_per_sec" : "400mb"
}
}
参数说明:
cluster.routing.allocation.node_concurrent_recoveries: 每个node上允许rebalance的片数量。
cluster.routing.allocation.cluster_concurrent_rebalance: 用来控制均衡力度，允许集群内并发分片的rebalance数量，默认为2。
cluster.routing.allocation.node_initial_primaries_recoveries: 该参数用来控制节点重启时，允许同时恢复几个主分片。默认是 4 个。如果节点是多磁盘，且 IO 压力不大，可以适当加大。
indices.recovery.max_bytes_per_sec: 该参数用来控制节点恢复时的速率。默认是 40MB。显然是比较小的，建议加大
