externalevents

External events sample

Features

• Reads the Name event payload from standard input asynchronously.
• Preserves the five-minute host timeout and the 30-second durable event timeout on the single-event orchestration.
• Demonstrates repeated typed EventChannel receives and verifies event order.
• Demonstrates cross-instance durable SendEvent.
• Runs a controlled expected timeout path that completes successfully only when the durable event wait times out.
• Cleans up only orchestration instances created by this run.

Prerequisites

Start a Durable Task Scheduler endpoint or emulator and set:

export DTS_CONNECTION_STRING="Endpoint=http://localhost:8080;TaskHub=default;Authentication=None"

Run

printf 'Taylor\n' | go run ./samples/externalevents

Expected result

The sample verifies Hello, Taylor!, receives three typed checkpoint events in order, sends a typed signal from one orchestration to another, and confirms the expected timeout scenario. On success it prints:

SAMPLE_OK externalevents

Cleanup

The sample terminates if needed and recursively purges only generated sample-externalevents-* orchestration instances before shutting down.

Noninteractive command

printf 'Taylor\n' | DTS_CONNECTION_STRING="$DTS_CONNECTION_STRING" go run ./samples/externalevents
