可以用 update-index-settings API 动态修改副本数:
PUT /my_temp_index/_settings { "number_of_replicas": 1 }
curl -XPUT http://192.168.0.200:9200/index_execution_20200414/_settings -d ‘{"number_of_replicas":1}‘
curl -XPUT http://192.168.0.200:9200/index_execution_20200414/_settings -d ‘{"number_of_replicas":0}‘
