Task:
Create a sample demonstrating the new poller auto-scaling feature in the Go client worker.
What I did:
Created a new sample called "autoscaling-monitoring" under cmd/samples/advanced. The sample is independent of config/development.yaml and can be copied to another project and run independently. It demonstrates how to enable and use the Auto Scaler and add a metrics endpoint for Prometheus. The README includes comprehensive instructions on how to run everything and provides a link to observe the new dashboards for viewing auto-scaling metrics.
Caveats:
The debate continues between using cmd/samples and new_samples. This sample doesn't really fit in either category as it's not a workflow sample—it's all about the worker configuration and adding a Prometheus endpoint. To avoid polluting either of the existing directories, I created a novel sample type: cmd/samples/advanced. Let me know what you all think about this approach.
PS:
To view the dashboards you will need this: cadence-workflow/cadence#7177
