Define transaction boundaries by applying @Transactional to atomic multi-step workflows to prevent partial commits. Specify propagation and isolation settings to ensure safe rollback behavior across multiple repositories in your Spring application.

Ensure idempotency and consistency by applying outbox patterns for message publishing. Define clear commit boundaries so database writes and external system calls remain synchronized without partial updates during failures.

Propagation and isolation settings depend on your workflow's concurrency and locking requirements. Analyze data access steps to recommend precise @Transactional configurations that prevent dirty reads and ensure safe transactional behavior.

You need the outbox pattern when a feature writes to the database and publishes messages to external systems. It ensures transaction consistency by capturing messages within the same transactional boundary as your data changes.

Yes, this approach specifically handles workflows spanning multiple repositories. It defines atomic boundaries to prevent partial commits and ensures proper locking and rollback behavior across all repository interactions.

Transactions roll back unexpectedly when external calls lack clear commit boundaries or proper idempotency. Define precise transactional boundaries and retry behavior to isolate external system failures from database commit semantics.
