You are going to implement a notification service that will send notifications to users through different channels.
For example, on an e-commerce platform, when a buyer purchases a product, the notification service should send both email and push notifications to the seller.
| Event | Noti channels | Noti target |
|---|---|---|
| Buyer sends chat message to seller | Email, Push | Seller |
| Buyer purchases product | Email, Push | Seller |
| Remind to pay for pending order | Push | Buyer |
| Purchased items are shipped | Push | Buyer |
- The service should be able to handle huge traffic spikes, e.g., sale events on double day 11.11.
- Notification channels should be configurable, e.g., the system should be able to send notifications via email, push, or both.
- Notification channel providers should be configurable and able to automatically switch over when one is down.
- For example, if we have providers A and B for email, the system should automatically switch to B when A is down.
- Feel free to add any additional features you think might be necessary.
- The team should be able to monitor and verify if notifications are sent successfully.
- The final outcome, if not runnable, should at least include unit tests that cover most scenarios.
