Hi,
I have a queue setup with max message count of 100 and as a ring queue. The
single client creating that queue will consume 1 message and then wait
indefinitely (for the purpose of my test). I am producing a total of 250
messages. As I would expect, qpid-tool reports that 250 messages have been
enqueued and 150 have been dequeued (presumably due to the oldest messages
being overwritten). Here is a snippet from qpid-tool
property arguments {u'qpid.max_count': 100,
u'qpid.policy_type': u'ring'}
property altExchange <NULL>
statistic msgTotalEnqueues 250 messages
statistic msgTotalDequeues 150
statistic msgTxnEnqueues 0
statistic msgTxnDequeues 0
statistic msgPersistEnqueues 0
statistic msgPersistDequeues 0
statistic msgDepth 100
However, when I resume my client, I would expect that it only will receive the
100 remaining messages on the queue, but instead it completes with all 250.
I'm slightly confused by this because the definition of a ring queue states :
""RING : start overwriting messages in a ring based on sizing. If head meets
tail, advance head". The behavior I want is for it to overwrite older messages
once the queue reaches max size.
We are using qpid .06, working on upgrading to .12.
Thanks in advance.
