Durable Temporal workflows are designed by separating orchestration logic from external interactions to ensure reliable state persistence. You can implement patterns like Saga, Actor Model, and Async Callbacks for long-running processes and microservice coordination.

Distributed transaction rollback is handled using the Saga pattern with compensation. This Temporal workflow pattern coordinates activities and compensations to reliably reverse operations if a long-running microservice process fails.

Temporal enforces determinism and idempotency by separating workflow logic from side effects, ensuring replay-compatible executions. This mechanism guarantees automatic state preservation and reliable restoration during distributed system failures.

You need the Actor Model pattern, implemented as Entity Workflows, for per-entity lifetime management and stateful coordination. This Temporal pattern is ideal when orchestrating long-running processes that require consistent state for specific entities.

The best way to orchestrate parallel tasks and external events is using Fan-Out/Fan-In and Async Callback patterns. These Temporal workflows coordinate parallel execution and manage external signals for reliable distributed system processing.
