This sample shows how we can implement frequent polling (1 second or faster) inside our Activity. The implementation is a loop that polls our service and then sleeps for the poll interval (1 second in the sample).
To ensure that polling Activity is restarted in a timely manner, we make sure that it heartbeats on every iteration. Note that heartbeating only works if we set the HeartbeatTimeout to a shorter value than the Activity StartToCloseTimeout timeout.
To run, first see README.md for prerequisites. Then, run the following from this directory in a separate terminal to start the worker:
dotnet run worker
Then in another terminal, run the workflow from this directory:
dotnet run workflow
This will show logs in the worker window of the workflow running.
