# a job is scheduled unless there is no prior digest notification that is not yet read (mail_reminder_sent: true).
|
|
# If we were to only set the mail_reminder_sent state at the end of the mail rendering an edge case of the following
|
|
# would lead to digest not being sent or at least sent unduly late:
|
|
# * Job starts and fetches the notifications for rendering. We need to fetch all notifications to be rendered to
|
|
# order them as desired.
|
|
# * Notification is created. Because there are unhandled digest notifications no job is scheduled.
|
|
# * The above can happen repeatedly.
|
|
# * Job ends.
|
|
# * No new notification is generated.
|
|
#
|
|
# A new job would then only be scheduled upon the creation of a new digest notification which (as unlikely as that is)
|
|
# might only happen after some days have gone by.
