Subject Intermediate solution set of delta iteration
Date Sun, 20 Mar 2016 17:12:46 GMT
Hi all,

Are there any approaches here I could get intermediate solution sets from
every delta iteration? I tried union but the compiler gave me the error: 
Exception in thread "main"
org.apache.flink.api.common.InvalidProgramException: Error: The only
operations allowed on the solution set are Join and CoGroup.
