django-graceful-session-cleanup 0.2.2

安装

安装包

pip install django-graceful-session-cleanup

将其添加到INSTALLED_APPS

INSTALLED_APPS = [
    ....
    'graceful_session_cleanup',
]

运行管理命令

python manage.py graceful_session_cleanup

有一些选项您可以使用

python manage.py graceful_session_cleanup --sleep-seconds 9 --delete-count 1000 --iteration-count 200

这将删除1000个过期的会话条目，等待5秒钟以便其他进程可以使用数据库，然后重复200次。根据数据库负载（假设删除需要1秒），这将需要(9s + 1s) * 200 = 2000s。

命令行上有帮助

$ python manage.py help graceful_session_cleanup
Usage: django graceful_session_cleanup [options]

Can be run as a cronjob or directly to clean out old data from the database (only expired sessions at the moment). Does this in a live db friendly way by never hogging the connection too long.
