Webhooks are essential in modern API interactions, as they eliminate the need for polling-based
architectures and significantly improve latency in distributed workflows by providing
near-instantaneous responses to changes, enabling more efficient and real-time data
synchronization across systems.
In this talk, I will demonstrate how to leverage PostgreSQL as a centralized message store for
queuing and managing webhook events with transactional integrity.
Additionally, I will cover the implementation of a dead-letter queue (DLQ) to gracefully handle failures,
cron jobs for managing recurring events, and a leader election mechanism to enforce an exactly-once
execution model, ensuring reliable and consistent event processing across distributed systems.
