public class ParallelExample extends DurableHandler<ParallelExample.Input,ParallelExample.Output>
Example demonstrating parallel branch execution with the Durable Execution SDK.

This handler processes a list of items concurrently using context.parallel():

  1. Each item is processed in its own branch (child context)
  2. All branches run concurrently and their results are collected
  3. A final step combines the results into a summary

The ParallelDurableFuture implements AutoCloseable, so try-with-resources guarantees join() is called even if an exception occurs.
