Workflows / States

Choice Workflows

Choice states are the decision engine of a Step Functions workflow, controlling how execution branches based on data, conditions, and runtime context. This collection of workflows demonstrates how Choice states evaluate inputs using JSONPath, comparison operators, and logical rules to dynamically route execution down different paths. From simple yes or no checks to complex multi-condition branching, these examples show how to build intelligent workflows that adapt in real time. You will see how Choice states enable validation gates, conditional processing, fallback handling, and business rule enforcement, making your state machines responsive, flexible, and aligned with real-world logic.

52 workflows

Model Drift Escalation

Model Training Pipeline

Escalation workflow for models flagged with performance drift. Applies a review hold, runs parallel re-evaluation and retraining, then routes to endpoint rollback or redeployment.

Express Model Validation

Model Training Pipeline

Lightweight express validation of a candidate model against a holdout test set. Used for fast shadow-mode evaluation before promoting to production traffic.

Express Sentiment Analysis

AI Document Analysis

Express workflow for rapid sentiment and tone analysis using Amazon Bedrock.

Content Moderation Pipeline

Content Moderation

End-to-end AI content moderation pipeline covering content ingestion, multi-label classification, human review routing, moderation action enforcement, classifier feedback, and outcome notification.

Express Spam Detection

Content Moderation

High-throughput express spam and phishing detection for inbound messages. Classifies content, waits for policy threshold check, then routes to auto-block or allow with feedback loop.

Vehicle Recall Pipeline

Vehicle Recall Management

This workflow models a complete end-to-end vehicle recall management pipeline using AWS Step Functions. It validates the recall notice, identifies affected vehicles, notifies registered owners, schedules dealership inspections, orders replacement parts, records regulatory compliance, and closes the recall case.

Recall Escalation

Vehicle Recall Management

This workflow handles escalation of a recall case where an initial inspection or parts order has failed. It re-validates the recall, enforces a brief processing Wait, then re-runs owner notification and parts ordering in parallel before re-scheduling inspection or closing the case with an escalation flag.

Express Vehicle Check

Vehicle Recall Management

This workflow provides a fast recall eligibility check for a single VIN. It identifies whether the vehicle is affected, and if so immediately schedules a dealership inspection, applying a brief Wait to allow appointment confirmation to propagate before completing with a Succeed or Fail terminal state.

Bulk Recall Processing

Vehicle Recall Management

This workflow processes a batch of affected vehicles concurrently using a Map state with a maximum concurrency of 3. For each vehicle, owner notification and parts ordering are run simultaneously in a Parallel state before scheduling the inspection appointment.
