- 2 separate tasks - DB and Provider
- DB to persist notification
- Provider to contact provider
- Each piece has separate retries
- Provider retries have configured back-off
In order to set a message as temporary-failure, we check if it is in pending status first.
Otherwise a delivery receipt for failure is set to permanent failure.
If the notification has a status == sending then update the status otherwise do not update the status.
In other words do not change the status more than once.
We were using two different queries to filter template stats to the past
7 days, plus today.
Since we’re storing both as short dates, we can now use the same query
for both.
0 | 1 | 2 | 3 | 4 | 5 | 6 | 7
-------|---------|-----------|----------|--------|----------|--------|-------
Monday | Tuesday | Wednesday | Thursday | Friday | Saturday | Sunday | Monday
So if we are on Monday, the stats should include today, plus everything
back to last Monday.
Previously the template stats query was only going back to the Tuesday.
This should mean the numbers on the dashboard always line up.
This means we will retain notifications for a full week and not
delete records that are 7 x 24 hours older than the time of the run of
the deletion task.
Also the task only needs to run once a day now, so I have changed
the celery config for the deletion tasks.
adapted to recording inserts and updates.
This removes need to manually create history tables.
Our code still remains in control of when history records are
created.

On the dashboard we want to show counts of notifications sent in the
last 7 days, plus today. So the API enpoint needs to accept an argument
to limit how many days worth of statistics it will return.
This is a bit fiddly at the DAO level because the date is just stored as
a string.
- when a provider callback occurs and we update the status of the notification, also update the statistics table
Adds:
- Mapping object to the clients to handle mapping to various states from the response codes, this replaces the map.
- query lookup in the DAO to get the query based on response type / template type
Tests around rest class and dao to check correct updating of stats
Missing:
- multiple client callbacks will keep incrementing the counts of success/failure. This edge case needs to be handle in a future story.
- SES sends a reference to allow us to identify the notification
- use this to update status
If source of email is one of our internal emails (invites or validations) - don't try and update a notification.
