transaction-consistency-designer

To define safe transaction boundaries in Spring, you scope atomic transactions around tightly-coupled database writes while moving external calls and message publications to asynchronous steps. This prevents long-running transactions and hidden consistency bugs.

You need an outbox pattern in backend design when publishing messages after database writes to guarantee reliable delivery and rollback. It ensures cross-service consistency by decoupling message publication from the main transaction scope.

Idempotency prevents duplicate side effects by assigning unique keys to operations, ensuring that retried external calls or message deliveries in cross-service workflows execute only once. This maintains data correctness during recoverability scenarios.

Yes, the transaction consistency designer works specifically with Kotlin and Spring workflows. It applies advanced consistency considerations to reactive or multi-service workflows to prevent rollback surprises and ensure recoverability.

You should use appropriate propagation and isolation settings that enforce one-transaction scopes around tightly-coupled steps. These settings prevent data loss and hidden consistency bugs by ensuring reliable rollback for business invariants.
