1. A list of repositories must be included within the scaling metric. Maintaining a list of repositories may not be viable in larger environments or self-serve environments.
2. May not scale quickly enough for some users' needs. This metric is pull based and so the queue depth is polled as configured by the sync period, as a result scaling performance is bound by this sync period meaning there is a lag to scaling activity.
3. Relatively large amounts of API requests are required to maintain this metric, you may run into API rate limit issues depending on the size of your environment and how aggressive your sync period configuration is.
4. The GitHub API doesn't provide a way to filter workflow jobs to just those targeting self-hosted runners. If your environment's workflows target both self-hosted and GitHub-hosted runners then the queue depth this metric scales against isn't a true 1:1 mapping of queue depth to the required runner count. As a result of this, this metric may scale too aggressively for your actual self-hosted runner count needs.
Example `RunnerDeployment` backed by a `HorizontalRunnerAutoscaler`:
