我有一个弹性搜索服务器,我从实时网站和Django管理命令查询。管理命令在格林威治标准时间凌晨3点使用celery beat来同步来自外部服务的数据。有时(但不是每次)运行此命令弹性搜索似乎崩溃,我在错误日志中收到以下错误。

我正在使用pyelasticsearch在我的settings.py文件中使用以下代码连接到Elastic Search:
try:
ES_CON
except NameError:
ES_CON = None
if not ES_CON:
ES_CON = ElasticSearch(ELASTICSEARCH_URI)
非常感谢任何帮助。
答案 0 :(得分:2)
我建议使用官方的Elasticsearch python客户端:elasticsearch-py具有可靠的连接处理,线程安全等。它也更快(根据作者,他是Elasticsearch团队的一员)。
然后,您可以将es = Elasticsearch()
放在tasks.py
的顶部,或者例如core.helpers
。 es
并从那里导入{{1}}。
