I am definitely missing something, but may be you can clarify a bit more. . . may be a more concrete use case that it would address? I know you mentioned join, but there is no guarantee that "all required" will arrive at the pre-defined time, right? Anyway, help me out here ;) > Expose a getOneFromEachConnection method in ProcessSession > ---------------------------------------------------------- > > Key: NIFI-2794 > URL: https://issues.apache.org/jira/browse/NIFI-2794 > Project: Apache NiFi > Issue Type: Improvement > Components: Core Framework > Affects Versions: 1.0.0 > Reporter: Pierre Villard > Assignee: Pierre Villard > Priority: Minor > > In case a processor has multiple incoming connections, it could be interesting to expose a method allowing users to get exactly one flow file per incoming connection in a row. > That could unlock opportunities such as performing join operations on datasets. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
