Conditional Approval Routing -- routes approval requests to different approval chains based on amount tier.

Input: requestId, amount, requester | Timeout: 300s

Output: requestId, amount, tier, processed

route_approval [SWITCH]
  ├─ low: mgr_only_approval

Workers

ClassifyWorker (car_classify): Worker for car_classify — classifies a request amount into a tier.

• amount < 1000: "low" (manager approval only)

• 1000 <= amount < 10000: "medium" (manager + director)

• amount >= 10000: "high" (manager + director + VP)

• amount >= 10000 → "high"

• amount >= 1000 → "medium"

Reads amount. Outputs tier.

ProcessWorker (car_process): Worker for car_process — marks a request as processed after all approvals.

Reads requestId, tier. Outputs processed.

Workflow Output

• requestId: ${workflow.input.requestId}
• amount: ${workflow.input.amount}
• tier: ${class_ref.output.tier}
• processed: ${proc_ref.output.processed}

Data Flow

car_classify: amount = ${workflow.input.amount} route_approval [SWITCH]: switchCaseValue = ${class_ref.output.tier} car_process: requestId = ${workflow.input.requestId}, tier = ${class_ref.output.tier}
