Clean up old events

Hi! I have local instaled Sentry 9.1.2. I faced with problem how clean up old events?
I tried use

/var/www/sentry/bin/python /var/www/sentry/bin/sentry cleanup --days 60 --project project

but this process working 3 days now and not finished! Maybe I have any variants how delete events per project? And may exist approach for check how many weight every project?
The processes in status sleep always.

In earlier versions of Sentry, we keep infinite event history by default. I recommend upgrading which brings this down to 90 days by default.

OK, Nice. But could I change “90 days by default” in newest version?

Yes you can but extending it beyond 90 days is not recommended.
