使用elasticdump复制索引

方法1: 使用node模块 - elasticdump
安装 npm install elasticdump
-g elasticdump example: elasticdump --input=http://production.es.com:9200/my_index --output=http://staging.es.com:9200/my_index --type=data 参考官网:https://www.npmjs.com/package/elasticdump

注:这个在数据量较大的时候可能会出错
方法二:reindex
POST _reindex {
"source": { "index": "twitter" }, "dest": { "index": "new_twitter" } } 参考官网:https://www.elastic.co/guide/en/elasticsearch/reference/6.4/docs-reindex.html
