Quick Answer
Distributed transactions across microservices: avoid 2-phase commit (distributed locks, complex, slow). Use Saga pattern instead: local transactions with compensating actions for rollback. Use idempotency to make retries safe. Accept eventual consistency where strong consistency isn't strictly required. Design operations to be naturally idempotent when possible.
Answer
Use Saga pattern for coordinated local transactions. Event-driven architecture ensures eventual consistency. Avoid global locks to maintain scalability.
