Feature Rollout with Average Latency Feedback

Introduction​

This policy rolls out new features based on average of latency as the rollout criteria. The average of latency is compared with thresholds to determine conditions for advancing, reversing, or resetting the rollout to its initial state. The rollout process consists of a series of steps that progress if the feature is considered healthy.

info

This blueprint is the same as Feature Rollout blueprint, with relevant fields highlighted in the aperturectl generated values file.
