About This Project

Highly Reliable Transactional Outbox Processor.

Features:

  • Processed 10K+ events/min with horizontal scaling by building a concurrent transactional outbox processor in Go.
  • Achieved zero message loss during crash simulations by designing atomic batch state transitions and time-based worker takeover within PostgreSQL transactions.
  • Reduced database round-trips by ~80% by batching 500 events per cycle and performing bulk status updates.
  • Ensured at-least-once delivery guarantees by combining persistence with reliable publishing to RabbitMQ
