> autoscaling/v2beta2 HorizontalPodAutoscaler added a spec.behavior field that allows scale behavior to be configured. Behaviors are specified separately for scaling up and down. In each direction a stabilization window can be specified as well as a list of policies and how to select amongst them. Policies can limit the absolute number of pods added or removed, or the percentage of pods added or removed. (#74525, @gliush) [SIG API Machinery, Apps, Autoscaling and CLI]
Yep, in the version I'm on (1.15) there's only global flags and config[1] which apply to all HPAs, but not all apps should scale the same way - our net facing glorified REST apps can easily scale up with, say, a 1-2m window, but our pipeline apps sharing a Kafka consumer group should be scaled more cautiously (as consumer group rebalancing is a stop-the-world event for group members)
