-------------------------------------
Summary: JmsSpout should support additional ack mode or should
have option for child classes
Key: STORM-2661
URL: https://issues.apache.org/jira/browse/STORM-2661
Project: Apache Storm
Issue Type: Improvement
Components: storm-jms
Affects Versions: 1.1.0
Reporter: Dhiraj Sardana
Priority: Minor
Currently , JmsSpout supports 3 acknowledge modes. But some of the queue
Providers (like Solace) supports some more ack modes. Like :
Sol_client_ack which acknowledges each message individually to support
Guaranteed Delivery.
As JmsSpout's 'jmsAcknowledgeMode' is private and setter has validations, so we
can't simply extend JmsSpout(and override required APIs only) to support this
additional features. We need to take the complete code.
JmsSpout reference Url
:https://github.com/apache/storm/blob/v1.1.0/external/storm-jms/src/main/java/org/apache/storm/jms/spout/JmsSpout.java
So, either there should be support for enhancements by child classes or
this additional ack mode(which seems generic requirement) should be included in
JmsSpout itself - we've some reference code which is working fine. can share
the same if required.
