Y Wikander commented on NIFI-4169: ---------------------------------- [~ijokarumawak]. I tested it. Yes, it covers the use case I was interested in. > PutWebSocket processor with blank WebSocket session id attribute cannot > transfer to failure queue > ------------------------------------------------------------------------------------------------- > > Key: NIFI-4169 > URL: https://issues.apache.org/jira/browse/NIFI-4169 > Project: Apache NiFi > Issue Type: Improvement > Components: Extensions > Affects Versions: 1.3.0 > Reporter: Y Wikander > Assignee: Y Wikander > Labels: patch > Attachments: > 0001-websocket-when-sendMessage-fails-under-blank-session.patch, > 0002-websocket-PutWebSocket-enhance-broadcast-support.patch > > > If a PutWebSocket processor is setup with a blank WebSocket session id > attribute (see NIFI-3318; Send message from PutWebSocket to all connected > clients) and it is not connected to a websocket server it will log the > failure and mark the flowfile with Success (rather than Failure) -- and the > data is effectively lost. > If there are multiple connected clients, and some succeed and others fail, > routing Failure back into the PutWebSocket could result in duplicate data to > some clients. > Other NiFi processors seem to err on the side of "at least once". -- This message was sent by Atlassian JIRA (v6.4.14#64029)
