I think Stephan meant Meteor, an old API when Flink was Stratosphere. This was never part of the code that made it to Apache.
Not sure if we want to remove the common API, as it provides a dataflow abstraction that is higher level than the JobGraph. Admittedly, I don't have a better argument other than "it might be useful some day" and happy to change my opinion :-) Kostas On Tue, Apr 21, 2015 at 5:49 PM, Henry Saputra <henry.sapu...@gmail.com> wrote: > Thanks for the explanation, Stephan.
