-------------------------------------------
Summary: ConsumeJMS processor losses messages on NiFi restart
Key: NIFI-2774
URL: https://issues.apache.org/jira/browse/NIFI-2774
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 0.7.0, 1.0.0, 1.1.0, 0.8.0
Reporter: Christopher McDermott
Priority: Critical
Fix For: 1.1.0, 0.8.0
ConsumeJMS processor uses auto-acknowledge mode. Unlike the deprecated
GetJMSQueue processor it does not provide a way to specify a different ACK mode
(i.e. client-acknowledge.) Using auto-acknowledge, acknowledges message
receipt from JMS *before* the messages are actually added to the flow. This
leads to data-loss on NiFi stop (or crash.)
I believe the fix for this is to allow the user to specify the ACK mode in the
processor configuration like is allowed by the GetJMSQueue processor.
