    常用操作命令

        "transient" : 
            {
              "index.indexing.slowlog.threshold.index.warn": "10s",
                "index.indexing.slowlog.threshold.index.info": "5s",

            }
    
    }'
    
    curl -XPOST '127.0.0.1:9200/_cluster/settings' -d '{
        "transient" : 
            {
