# What this PR does https://www.loom.com/share/18cc445117de4895a10892d56c7d3699 In preparation to upgrade our cloud databases, this PR makes some minor changes which, after testing locally, allowed the `POST /<integration_type>/<alert_channel_key>` endpoints to successfully receive incoming alerts and queue the celery tasks. I've tested all of the defined `POST /integrations/v1/<integration_type>/<alert_channel_key>` endpoints by sending `POST` requests to an integrations' URL while the MySQL database was down, bringing the database back up, and ensuring the alerts were created. ## Some other findings - the integration heartbeat endpoints will not work as we interact w/ the database to persist the incoming heartbeat instance - if the integration was created in the last 180 seconds, incoming alerts will fail due to the way we cache the integration IDs ([code](https://github.com/grafana/oncall/blob/dev/engine/apps/integrations/mixins/alert_channel_defining_mixin.py#L47-L50)) - The `create_alert` celery task is set to `max_retries=None` and `retry_backoff=True`. This means that the queued tasks will continue retrying forever w/ an exponential backoff, until the alerts can be created in the database (ie. when the database is back online). ## Checklist - [ ] Unit, integration, and e2e (if applicable) tests updated (N/A) - [ ] Documentation added (or `pr:no public docs` PR label added if not required) (N/A) - [ ] `CHANGELOG.md` updated (or `pr:no changelog` PR label added if not required) (N/A) |
