Hi Timo, thanks for your answer. I think my elaboration are not too much heavy so I imagine I will have no advantages to "parallelize" streams.
In my mind I have this pipeline: <http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/file/n13969/Screen_Shot_2017-06-22_at_19.png> And this is exactly what I want develop: a need a pipeline where a node runs fixed operation and forward elaborated data to the next and so on. How can I obtain this? If I understand "chaining" considers the possibility of execute multiple operations on same thread to improve performance. -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/About-nodes-number-on-Flink-tp13927p13969.html Sent from the Apache Flink User Mailing List archive. mailing list archive at Nabble.com.
