Temporal Training Session

Schedule: Stream #1 - 101

• These courses introduce the Temporal platform architecture and establish the fundamentals of Temporal application development.
• You'll encounter several common problems faced by Temporal developers, understand why they occur, and how to identify, solve, and avoid them.
• You’ll also become familiar with the Temporal Web UI, CLI, SDK, and their relationship to server-side events.

Schedule: Stream #2 - Advanced Topics

1. RECAP: Core Concepts: Workflow, Activity, Worker (10 minutes)

• Workflow: Defines the business process logic; durable, stateful, and replayable
• Activity: Encapsulates external, potentially unreliable business logic (e.g., API calls)
• Worker: Runs Workflow and Activity code; connects your application to the Temporal service Task Queue

2. Flow Control: Await, Timer and Signal (20 minutes)

• Await: Pause Workflow execution then wake up by Signal or Timer
• Timer: Durable timer on the server side. Updatable by Signals.
• Signals: Mechanism to send external events/data to running Workflows
• Use cases: approvals, manual interventions, status checks

3. Exercise: Adding Flow Control to Workflow (25 minutes)

• Implement Activities: withdraw, deposit, refund
• Await for approval
• Add a Signal for approval

4. Event History (30 minutes)

• Introduction to Temporal’s Event History: every Workflow Execution is recorded as a sequence of events
• How to inspect Event History in the Temporal UI
• Using Event History for debugging and understanding Workflow progress

5. Replay & Determinism (30 minutes)

• Explanation of Workflow replay: how Temporal ensures reliability and state recovery
• Determinism: why Workflow code must be deterministic
• Common pitfalls and best practices for writing deterministic Workflows
