Thank you for your reply, this is new information for me, Regarding the algorithm, i gave it a better look and i don't think it will work with joining. When looping over the Edge set (u,v) we need to be able to write and read A[u] and A[v]. If i join them it will create a new instances of that value and it doesn't matter if it's changed in one instance.
For example i have the following edges: u v 1 2 1 3 With vertices and values: 1 a 2 b 3 c If i join them i get: u v u' v' 1 2 a b 1 3 a c If i loop over the joined set and change the u' value of the first instance to "d" then in my next loop step it will be 'a'. -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Looping-over-a-DataSet-and-accesing-another-DataSet-tp9778p9784.html Sent from the Apache Flink User Mailing List archive. mailing list archive at Nabble.com.
