Re: About Operator and OperatorBase

2015-04-22 Thread Kostas Tzoumas
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

I think the main difference to the Java API is right now that the JavaAPI is fluent and the common API is compositional. Otherwise there is not much in the common API any more. Not sure whether this warrants an extra API... On Wed, Apr 22, 2015 at 3:52 PM, Kostas Tzoumas ktzou...@apache.org

Re: Fault Tolerance for Flink Iterations

Hi Stephan, thanks for your answer! I thought about this, too, but I am not sure if this solves to problem. I think it works if there is only a temporary failure an the job can be restartet with the same dop. But it does not work if one node is permanently lost and the dop needs to be adjusted. If

Re: Fault Tolerance for Flink Iterations

I think it should circumvent many of the problems. If you re-submit the program from the client with a lower DOP, all intermediae state (saved by you in files) will be re-partitioned, because no assumptions about prior properties are made. I may not be getting the whole picture here, so sorry, if
