> Autoscaling is a feature of google cloud dataflow runner that adds/removes
> worker nodes dynamically as the job runs. It can behave in a different way
> creating different test (runtime) results in consequent runs. In integration
> tests (such as IOIT but others also apply) we don't need such nondeterminism
> and it's best to have a fixed number of workers for every test execution.
> IOITs use autoscaling but they shouldn't. This issue was created to disable
> it and set a fixed number of workers.
> Side note: autoscaling is already disabled in Nexmark and load tests of core
> operations.
