------------------------------------------
Summary: Disable key group alignment for determining source
parallelism
Key: FLINK-32119
URL: https://issues.apache.org/jira/browse/FLINK-32119
Project: Flink
Issue Type: Bug
Components: Autoscaler, Kubernetes Operator
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: kubernetes-operator-1.6.0, kubernetes-operator-1.5.1
After choosing the target parallelism for a vertex, we choose a higher
parallelism if that parallelism leads to evenly spreading the number of key
groups.
For one, sources don't have keyed state, so this adjustment does not make sense.
For another, we internally limit the max parallelism of sources to the number
of partitions discovered. This makes the adjustment even less meaningful.
