使用bulk API 增加入庫速度
初次索引的時候，把 replica 設定為 0
增大 threadpool.index.queue_size 1000
增大 indices.memory.index_buffer_size: 20%
index.translog.durability: async –這個可以非同步寫硬碟，增大寫的速度
增大 index.translog.flush_threshold_size: 600MB
增大 index.translog.flush_threshold_ops: 500000

–節點下線時，把所有後綴為 -2的從叢集中排除
curl -XPUT http://127.0.0.1:9200/_cluster/settings
{ "transient" :
{"cluster.routing.allocation.enable" : "all", "cluster.routing.allocation.exclude._name":".*-2"}
}
curl -XPUT ip:9200/_cluster/settings -d
'{
"transient": {
"logger.discover": "DEBUG"
}
"persistent": {
"discovery.zen.minimum_master_nodes": 2
}
}'
—批量指定節點下線
