Pierre Villard updated NIFI-2794: --------------------------------- Attachment: image.png The idea was to cover this kind of situation: !image.png! Example: I have a processor A going through a list of IDs and generating one FlowFile per ID. I have a processor B fetching data from one source for the given ID and the processor C does the same from another source. The processor D could use this method to get FlowFiles from both B and C for the same ID and join the data into one flow file. I do realize now that this would be covered by the ongoing work with NIFI-2590, NIFI-1926, NIFI-2735. There are more general patterns to cover here and this, without any doubt, can be achieved in a more elegant/general way. > 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)
