es_result = es_client.bulk(index="log_index",doc_type="log_index", body= result)
es_client.indices.flush()
 

說明 使用es_client.bulk方法 可以不建立索引index，也能批量插入成功

from elasticsearch import Elasticsearch
from elasticsearch import helpers
import datetime
es_client = Elasticsearch(["127.0.0.1:9200"], timeout=20)
es_client.indices.create(index='d_kl', ignore=400)
result = []
action = {
                "_index": "d_kl",
                "_type": "d_kl",
                "_source": {
                  "data": "資料"
            }
            }
result.append(action)
helpers.bulk(es_client, result)
es_client.indices.flush()
