ES5以上版本可以设置flush的interval吗？

In previous versions Elasticsearch allowed to specify index level setting as defaults on the node level, inside the elasticsearch.yaml file or even via command-line parameters. From Elasticsearch 5.0 on only selected settings like for instance index.codec can be set on the node level. All other settings must be set on each individual index. To set default values on every index, index templates should be used instead.

curl -XPUT 'localhost:9200/my_index/_settings' -d '

{

    "index" : {

        "translog" : {

            "flush_threshold_size" : "512mb"

        }

    }

}'
