Title:
Notifications chunking needs to chunk per-cron-run, not per-message
Status in Mahara ePortfolio:
In Progress
Bug description:
In Bug 778254, we added a system to make it so that notifications to
large numbers of users are processed in chunks, instead of all at
once.
So, when you post to the mahara.org news forum, to which 30,000 users
are subscribed, each run of the activity_process_queue cron task only
sends out 500 notifications, instead of sending out all 30,000 on the
first run.
The problem, is that this limit is enforced per notification, *not*
per cron task. So if you make two news forum posts a minute apart,
they'll both get processed each time activity_process_queue runs, and
they'll both send out 500 notifications, making 1000 on each cron run.
Make 5 posts, and you get 2500 notifications, etc.
