What is the Transactional Outbox Pattern?

Saves events in your DB transactionally, then relays via worker. Fixes dual-writes.

Does Transactional Outbox work with MongoDB?

Perfectly—embed in docs, atomic inserts, partial indexes for speed.

Outbox handles local writes; Saga orchestrates multi-service compensations.

Dual-writes kill 70% of microservices deployments. Enter Transactional Outbox: save your sanity, one atomic insert at a time.
