To prevent partial commits in Spring, you must define clear transaction boundaries aligned with business invariants. This ensures multi-repository operations execute within a single transactional span, rolling back all changes if any step fails.

You need an outbox pattern for transactional consistency when publishing messages after database writes. It prevents data inconsistencies by storing messages in the same transaction, ensuring reliable post-commit delivery without partial commits.

The best way to configure @Transactional propagation and isolation levels is to map them precisely to your workflow steps. Proper configuration prevents data anomalies and ensures safe concurrent access during multi-step operations.

Handling rollback rules for external calls requires explicit transactional checks and robust error handling. You should isolate external calls from the main database span or use outbox patterns to prevent partial commits.

Your Kotlin service suffers from duplicate processing and data inconsistencies due to missing idempotency keys and improper transaction boundaries. Applying precise @Transactional propagation and outbox patterns resolves this.
