Can you define exactly what `orderedPreferredReplicas` policy is in the PR description? I only see a few examples like: > To make the solution more flexible, we allow specifying a list of preferred replica groups instead of a single group. This is particularly useful during rollouts, where Uber progressively deploys changes to replica groups 0, 1, then 2. For example, during the rollout to replica group 0, setting orderedPreferredReplicas = [0, 1] ensures canary traffic avoids replica group 2. In general, this approach limits the blast radius to approximately 1/(n-1) during replica group–based rollouts. But we do not have a formal definition. -- This is an automated message from the Apache Git Service.
