Notification Sending System responsible for delivering notifications or messages to recipients through various communication channels.
The notification sending system consists of the following components:
- Web App: REST API implemented in golang which receives and sends the notifications for processing.
- Database: A PostgreSQL database is used to store the notifications. It retains metadata and status information about each notification, enabling tracking and auditing of the notification sending process.
- Message Queue: A message queue implemented using Redis Streams. It acts as a buffer for storing notifications before they are sent to their respective channels.
- Integrations: External services which specializes in processing notifications by channel.
- Email Integration (mailgun): An email delivery service that provides an API for sending emails. It consumes email notifications from the Redis Stream and sends them as email messages to the specified recipients.
- SMS Integration (twilio): An external service that specializes in sending SMS messages. It consumes SMS notifications from the Redis Stream and sends them as SMS messages to the intended recipients.
- Slack Integration (slack): A service or API integration with the Slack messaging platform. It consumes notifications from the Redis Stream and sends them as messages to the designated Slack channels.
