Oleg Zhurakousky commented on NIFI-2794: ---------------------------------------- Had an off-line discussion with Pierre but to stay true to ASF world below is the summary of it Based on our discussion we both realized that the use case Pierre was trying to address falls into the category of basic aggregation and as Pierre already pointed out it is tracked by several issues already NIFI-2590, NIFI-1926, NIFI-2735. So I think it is fair to close this issue as won't fix after linking it to any of the once mentioned above especially NIFI-1926 since it already attempts to collect variety of use cases. Also, linking [~mattyb149] since he is involved in the overall effort as well. > 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 > Attachments: image.png > > > 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)
