Design deterministic Temporal workflows by separating workflow logic from activities, enforcing determinism, and relying on automatic state preservation to orchestrate resilient long-running processes. This ensures reliable execution across microservices and databases.

Implement a saga pattern for distributed transactions using Temporal workflows to define compensating activities. This provides fault-tolerant orchestration that automatically rolls back or retries failed steps within complex business transactions.

Handle long-running processes by defining Temporal activities with heartbeat-based progress monitoring. This enables automatic state preservation and fault-tolerance, allowing the workflow to track activity execution and recover seamlessly from transient failures.

Yes, you can use Temporal workflows for human-in-the-loop processes by applying async callback patterns. This allows the workflow to wait for external events and human input while maintaining deterministic state and reliable execution.

Execute parallel tasks and aggregate results by applying the Fan-Out/Fan-In design pattern within your Temporal workflow. This orchestrates concurrent activity execution across distributed systems and aggregates their outputs into a single deterministic result.

Temporal workflows fail due to non-deterministic errors when workflow code performs non-deterministic operations instead of delegating side effects to activities. Enforcing strict workflow vs activity separation ensures deterministic replay and reliable state management.
