All Implemented Interfaces:

public class ChildContextExample
extends DurableHandler<GreetingRequest,String>

Example demonstrating child context workflows with the Durable Execution SDK.

This handler runs three concurrent child contexts using runInChildContextAsync:

1. Order validation — performs a step then suspends via wait() before completing
2. Inventory check — performs a step then suspends via wait() before completing
3. Shipping estimate — nests another child context inside it to demonstrate hierarchical contexts

All three child contexts run concurrently. Results are collected with DurableFuture.allOf(software.amazon.lambda.durable.DurableFuture<T>...) and combined into a summary string.
