    这是一个创建于 1573 天前的主题,其中的信息可能已经有所发展或是发生改变。

    我使用开源 BI 工具 Superset 搭了一个业务看板,其它方面没得说,确实挺棒的

    但就是有一个问题:在每次进入 Dashboard 的时候,会出现这样的报错:

    需要刷新很多次才能好

    完整报错代码如下:

       Traceback (most recent call last):
      File "/root/.pyenv/versions/3.6.5/envs/venv-3.6.5/lib/python3.6/site-packages/sqlalchemy/engine/base.py", line 755, in _commit_impl

        dbapi_connection.commit()
    sqlite3.OperationalError: database is locked
    
    The above exception was the direct cause of the following exception:

    sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) database is locked
    (Background on this error at: http://sqlalche.me/e/e3q8)
    

    初步判断是 sqlite3 的问题,在读数据库的时候遇到锁了,但是咱 python 太菜了,不知道有什么好的方法可以改一下(例如增加等待时间啥的)

    因此希望求助各位大佬,能解决的给一个大红包,拜谢了

    如果数据很多,并发也多的话,sqlite 不算是好的数据库。。

    @Neenjage 没有,我现在用最粗暴的办法,开一个 supervisor,遇到这个报错就 restart 整个 superset,这样刷新后就能正常进入报表
