Why is determinism strictly required in Temporal workflows?

Temporal uses event sourcing to replay workflows to their current state. If the code is non-deterministic (e.g., using random numbers or system time), the replay will produce different results than the original execution, causing a failure.

What is the main difference between a Workflow and an Activity?

Workflows handle orchestration logic and decision-making and must be deterministic. Activities handle all external interactions like API calls or database writes and can be non-deterministic.

When should I avoid using workflow orchestration?

Orchestration is overkill for simple CRUD operations, stateless request/response APIs, or real-time streaming where low-latency is prioritized over guaranteed state persistence.

How does the Saga pattern help with distributed transactions?

The Saga pattern manages multi-step processes by registering compensating actions for every step, allowing the system to roll back gracefully if a failure occurs during execution.

Cloud Infrastructure

Designs durable, distributed workflows using Temporal principles to ensure resilience and consistency across microservices.

This skill empowers developers to architect reliable distributed systems using Temporal's workflow orchestration patterns. It provides expert guidance on separating orchestration logic (workflows) from side-effect-prone tasks (activities), implementing the Saga pattern for distributed transactions, and ensuring execution determinism. Whether building complex order fulfillment pipelines, long-running business processes, or infrastructure automation, this skill provides the implementation patterns needed to ensure your system maintains state integrity and recovers gracefully from infrastructure failures.
