Github user akunft commented on the pull request: https://github.com/apache/flink/pull/1066#issuecomment-135830165 After thinking about it, I would change the behavior so that the config is only for defining akka specific settings. The default parallelism of the operators can be set via ```setParallelism```, just like in the local environment. Otherwise, we had to use ```parallelism.default``` to set the operators parallelism, which is confusing imo. This also goes in line with the configuration description on the website. What do you think? In any case, I will create unit tests and update the PR once we decided on a version.
