Python MongoDB-服务器状态非常慢
当我运行一个运行大约50个线程的多线程程序时,每个线程中都有数据库操作,mongodb运行太慢,然后服务就会停止。在Mongodb日志中,我看到以下消息:Python MongoDB-服务器状态非常慢,python,multithreading,mongodb,Python,Multithreading,Mongodb,当我运行一个运行大约50个线程的多线程程序时,每个线程中都有数据库操作,mongodb运行太慢,然后服务就会停止。在Mongodb日志中,我看到以下消息: 2017-12-13T09:24:50.226+0330 I COMMAND [ftdc] serverStatus was very slow: { after basic: 71, after asserts: 307, after backgroundFlushing: 358, after connections: 622, aft

这是我的线程代码:
def processor(*data):
for item in data[0]:
try:
col_articles_data.update({'_id': item['id']}, {'$set': {'processed': True}})
except:
Debug.PrintException()
我该怎么办?这表明您的mongodb需要的RAM比您配置的要多。我可以想出两种解决问题的方法:
- 增加Docker的RAM资源,以防它运行Docker容器()
- 关闭其他耗尽RAM的应用程序,如web浏览器或邮件客户端
