Rate limit replica scale up after parameter change

Open bowei opened this issue 4 years ago • 11 comments

After a configuration update, it is possible for the number of replicas to experience a large change (e.g. from 1k replicas => 2k), overwhelming the other parts of the infrastructure.

We should have a tunable scale up rate of change parameter such as "scale_up_replicas_per_second" that can control how fast we increase replica counts.

Note: it can default to infinity which is the policy today.
