[jira] [Commented] (AMQ-2217) Message delivery to selector based
consumers pauses if selector leaves messages on the queue.
[ https://issues.apache.org/jira/browse/AMQ-2217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13159325#comment-13159325 ]

------------------------------------
Does this mean that there is no plan to fix it in future versions of ActiveMQ and not Appollo ?

> Key: AMQ-2217
> URL: https://issues.apache.org/jira/browse/AMQ-2217
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.1.0, 5.3.0
> Environment: Windows XP Professional 2002, Service Pack 2, Intel Pentium D 3ghz, various 1.5 and 1.6 versions of jdk
> Reporter: Jar Lyons
> Assignee: Gary Tully
> Fix For: 5.4.1
>
> Attachments: DiscriminatingConsumerLoadTest.java
>
>
> I have written a test case which will demonstrate the difference between the following two scenarios:
> 1. Producer sending dissimilar JMSType messages to a queue, with a client consuming all messages (no selector).
> 2. Producer sending dissimilar JMSType messages to a queue, with a client consuming every other message (using selector).
> With a large enough size of test messages (for my environment about 5k), scenario 2 will fail with delivery to the consumer halted, while scenario 1 will not.
> Test Output:
> waiting for consumer to pause ... consumer: 0, producer: 0
> waiting for consumer to pause ... consumer: 200, producer: 5000
> waiting for consumer to pause ... consumer: 200, producer: 5000
> waiting for consumer to pause ... consumer: 200, producer: 5000
> waiting for consumer to pause ... consumer: 200, producer: 5000
> waiting for consumer to pause ... consumer: 200, producer: 5000
