Webhooks: Delete Old Per-event Records

Introduction

As the volume of data stored in the webhook_event, webhook_delivery, and webhook_delivery_attempt tables continues to grow, it's essential to implement a mechanism for deleting old per-event records. This is crucial to prevent the ever-increasing disk space usage and ensure efficient data management. In this article, we'll explore various approaches to delete old per-event records, including retention periods, API endpoints, and explicit deletion.

Retention Periods

One obvious solution is to implement a retention period for deleting events and their associated deliveries. This approach involves setting a time window, after which events and deliveries are automatically deleted. The retention period can be configured to allow operators to select their desired tradeoff between tolerating receiver downtime and reclaiming storage in a timely manner.

Benefits of Retention Periods

• Efficient data management: By implementing a retention period, you can ensure that only relevant data is stored, reducing the risk of data overload and improving system performance.
• Configurable: The retention period can be configured to suit the specific needs of your application, allowing operators to balance the tradeoff between receiver downtime and storage reclaiming.
• Guaranteed reliable delivery: With a retention period, you can guarantee reliable delivery of events within the specified time window.

Challenges of Retention Periods

• Limited guarantee: If a receiver is unavailable for longer than the retention period, events dispatched to it may be deleted even if they were not successfully delivered.
• Complexity: Implementing a retention period requires careful consideration of the tradeoff between receiver downtime and storage reclaiming.

API Endpoints for Deleting Webhook Events

An alternative approach is to add an API endpoint for deleting a webhook event by ID. This approach allows receivers to explicitly delete events they no longer need, ensuring that only relevant data is stored.

Benefits of API Endpoints

• Explicit deletion: Receivers can explicitly delete events they no longer need, ensuring that only relevant data is stored.
• Improved data management: By allowing receivers to delete events, you can improve data management and reduce the risk of data overload.

Challenges of API Endpoints

• Coordination: When multiple receiver endpoints are in use, operators may need to coordinate between themselves about which events may be deleted.
• Events with no interested receivers: Events that no receivers were subscribed to won't be deleted, since no receiver would ever have seen their UUID to say "yeah, I got this one".

Explicit Deletion

A third approach is to implement a way to explicitly delete everything older than a specified time. This approach allows operators to delete old events and deliveries on demand, ensuring that only relevant data is stored.

Benefits of Explicit Deletion

• Flexible deletion: Operators can delete old events and deliveries on demand, ensuring that only relevant data is stored.
• Improved data management: By allowing operators to delete old events and deliveries, you can improve data management and reduce the risk of data overload.

Conclusion

Deleting old per-event records is a crucial aspect of data management in webhook systems. By implementing a retention period, API endpoints, or explicit deletion, you can ensure efficient data management and reduce the risk of data overload. Each approach has its benefits and challenges, and the choice of approach depends on the specific needs of your application.

Recommendations

• Implement a retention period: A retention period is a good starting point for deleting old per-event records. It allows operators to configure the tradeoff between receiver downtime and storage reclaiming.
• Add API endpoints: API endpoints for deleting webhook events can improve data management and reduce the risk of data overload.
• Implement explicit deletion: Explicit deletion allows operators to delete old events and deliveries on demand, ensuring that only relevant data is stored.

By following these recommendations, you can ensure efficient data management and reduce the risk of data overload in your webhook system.

Future Work

• Implement a more sophisticated retention period: A more sophisticated retention period could take into account factors such as event type, receiver availability, and storage capacity.
• Improve API endpoints: API endpoints for deleting webhook events could be improved to include features such as event filtering and deletion scheduling.
• Develop a data management framework: A data management framework could be developed to provide a unified approach to data management in webhook systems.
