type MetricsAutoScalingConfig

type MetricsAutoScalingConfig struct {
	URL              string  // URL to contact Prometheus store on
	TargetQueueLen   int64   // Queue length above which we will scale up capacity
	ScaleUpFactor    float64 // Scale up capacity by this multiple
	MinThrottling    float64 // Ignore throttling below this level
	QueueLengthQuery string  // Promql query to fetch ingester queue length
