Error handling system with PostgreSQL logging and rate-limited notifications

Log errors and avoid sending too many emails

Use case

Most of the time, it’s necessary to log all errors that occur. However, in some cases, a scheduled task or service consuming excessive resources might trigger a surge of errors.

To address this, we can log all errors but limit alerts to a maximum of one notification every 5 minutes.

What this workflow does

This workflow can be configured to receive error events, or you can integrate it before your own error-handling logic.

If used as the primary error handler, note that this flow will only add a database log entry and take no further action. You’ll need to add your own alerts (e.g., email or push notifications). Below is an example of a notification setup I prefer to use.

At the end, there’s an error cleanup option. This feature is particularly useful in development environments.
