> The autoscaler currently sets the parallelism overrides via the Flink config {{pipeline.jobvertex-parallelism-overrides}}. Whenever the user posts specs updates, special care needs to be taken in order to carry over existing overrides. Otherwise the job will reset to the default parallelism configuration. Users shouldn't have to deal with this. Instead, whenever a new spec is posted which does not contain the overrides, the operator should automatically apply the last-used overrides (if autoscaling is enabled).
