Why is determinism critical in workflow orchestration?

Workflows function as state machines that must be able to replay history identically to recover state after an infrastructure failure.

What is an Activity Heartbeat?

A heartbeat is a periodic signal sent by a long-running activity to notify the orchestrator that it is still making progress, preventing unnecessary timeouts.

What is the fundamental rule for Workflows vs. Activities?

Workflows should only contain orchestration logic and must be deterministic, while Activities handle all external interactions like API calls and database writes.

How does this skill help with distributed transactions?

It provides implementation patterns for the Saga pattern, which uses registered compensating actions to roll back previous steps if a workflow failure occurs.

When should I avoid using workflow orchestration?

Orchestration is typically unnecessary for simple CRUD operations, stateless request/response APIs, or high-speed real-time streaming.

Productivity & Workflow

Designs resilient, durable distributed systems using Temporal orchestration patterns and fault-tolerant architecture principles.

This skill provides specialized architectural guidance for building reliable distributed systems using Temporal. It enables developers to implement complex, multi-step business processes by enforcing a strict separation between orchestration logic (Workflows) and external interactions (Activities). Users can master critical patterns such as Sagas for distributed transactions, entity workflows for state management, and fan-out/fan-in for parallel execution. The skill ensures system reliability by guiding users through determinism constraints, idempotency requirements, and automatic state preservation, making it essential for building production-grade microservice orchestrations and long-running workflows.
