Content Issue

Hello,

I use Temporal's Cloud Metrics to scale automatically my workers cluster. I was fetching the metric every ~10 seconds and got hit with rate limit. It is not mentioned anywhere that this API has rate limit. There is a warning about cardinality (which I made sure is low) and that's it about limitation. No mention of this limit in Limit as well.

The error message

Client error '429 Too Many Requests' for url 'https://metrics.temporal.io/v1/metrics?metrics=temporal_cloud_v1_approximate_backlog_count'
For more information check: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/429

Could you add documentation about the rate limit of Temporal's Cloud Metrics?

Thanks
