Your @EventListener Fires Before the Transaction Commits⚙️

Short summary

Spring's @EventListener fires mid-transaction before commit, causing stale reads. @TransactionalEventListener(AFTER_COMMIT) prevents stale reads but can silently drop events on listener failure. For mission-critical events, use the outbox pattern to guarantee reliable delivery tied to the database transaction.

• •@EventListener fires before commit; other DB connections see stale state until transaction completes
• •@TransactionalEventListener(AFTER_COMMIT) fixes visibility but loses events if the listener fails post-commit
• •Outbox pattern ensures reliable event delivery by writing events to the database within the same transaction
